MetaMask browser plugin: new report criticises high fees and phishing threats

The MetaMask crypto wallet is one of the most popular in the industry – but according to a new report, not all that glitters behind the orange fox’s facade is gold.

A recent blog post by freight and trade logistics blockchain network Freight Trust, which looks into the inner workings of MetaMask, reveals: The wallet has a dark side.

The far from flattering report, titled „Unmasking MetaMask“ (translates roughly to „Metamask without a mask“), claims that the popular Bitcoin Evolution crypto wallet is prioritising its commercial success over end-user security and potentially exposing users to unnecessary risks.

What does the MetaMask criticism consist of?

The first criticism lies with MetaMask’s 0.875% service fee, which is added to swap fees and gas prices.

„If you use MetaMask Swap, you get this on-top of the existing 0.3% Uniswap fee, for an effective fee of at least 1.175% per trade.“

The report adds that exchanges like 1inch do exactly what MetaMask does, without the high fees or 1.5x gas multiplier. There are also some discrepancies in how the wallet calculates gas prices – although that was said to have been improved in mid-December 2020.

The report also alleges that MetaMask engages in some „shady blacklisting practices“ by keeping an updated list of banned websites. There is also an allegation of potential token balance manipulation through holding a closed-source MetaSwap contract.

The blog post further alleges that MetaMask stores all trading data in plain text on its backend. This opens end users up to targeted phishing attacks, as hackers would know they are using this specific wallet – just as they did with Ledger customers.

Just like Ledger, MetaMask has also published a guide on phishing prevention and private key storage, however this is little consolation to users who have already lost cryptocurrencies such as Bitcoin (Go to Buy Bitcoin Cheap Guide) or Ethereum due to criminal activity on these platforms.

MetaMask (@metamask_io) on 15 February 2021:

„With MetaMask, private keys are stored only on your device. Only you have access to them. Keep them secret & you keep your wallet secure. Most losses are the result of phishing attempts.“

Metamask’s codebase and potentially intrusive tracking practices are further criticised.

Giełdy nadal borykają się z problemami ze skalowaniem i łącznością, ponieważ wolumen osiąga nowe ATH każdego dnia w parze z ceną aktywów cyfrowych.

Historyczne zyski Bitcoina powodują ciągłe problemy na giełdach kryptowalut

W czwartek Bitcoin Revolution przekroczył 40000 USD, a następnie zapewnił możliwość kupna dipu ze spadkiem do 36550 USD, ale ludzie nie mogli z tego skorzystać, ponieważ nie mogli uzyskać dostępu do platform. Dzisiaj BTC przekroczył 41 960 USD.

Zarówno w środę, jak i czwartek w Coinbase wystąpiły problemy z łącznością .

„Jesteśmy świadomi i badamy problemy z łącznością w Coinbase i Coinbase Pro w aplikacjach internetowych i mobilnych. Pracujemy szybko, aby przywrócić normalną obsługę ”- zauważyła giełda z siedzibą w San Francisco, która w zeszłym miesiącu złożyła wniosek o IPO w SEC z wyceną w kucyka 28 miliardów dolarów.

To nie pierwszy raz, kiedy społeczność kryptowalutowa od dawna narzeka, nawet przed wybuchem byka w 2017 roku, bez żadnego rozwiązania.

Inna popularna giełda kryptowalut , Binance , boryka się z podobnymi problemami ze skalowaniem. Jego dyrektor generalny, Changpeng Zhao, obiecał zwiększyć pojemność serwerów podczas grudniowej przerwy.

Te zakłócenia na giełdach kryptograficznych wynikają z gwałtownych wzrostów cen, które przyciągają do nich coraz większy ruch. Kiedy w czerwcu BTC przekroczyło próg 10 tysięcy dolarów, Coinbase odnotował pięciokrotny wzrost ruchu w ciągu czterech minut.

Ruch w Coinbase wzrósł z 23,73 miliona w październiku do 47,97 miliona w grudniu, według publikacji Similar Web. W tym samym czasie ruch Binance wzrósł z 32,5 miliona do 56,27 miliona.

Wolumen na giełdach również osiągnął nowe rekordy

„Binance doświadcza wolumenów ATH. Użytkownicy mogą doświadczyć pewnych opóźnień z powodu ekstremalnej zmienności rynku ”- napisała na Twitterze giełda w piątek.

Podczas gdy Binance odnotowuje „szalony ruch”, Bitfinex odnotował ponad 1 miliard USD w BTC / USD w ciągu zaledwie ostatnich 24 godzin. „Wolumen i ruch OKEX osiągnął ostatnio wysoki poziom”, powiedział Lennix Lai.

W międzyczasie Coinbase cieszy się dużym zainteresowaniem ze strony instytucji. Przez cały 2020 rok Coinbase, między innymi, doświadczył dużych odpływów bitcoinów, które ostatnio znacznie przyspieszyły i zostały powiązane z zakupami instytucjonalnymi.

Coinbase był głównym partnerem wykonawczym, który zainicjował zakup Bitcoin przez MicroStrategy . W tym tygodniu giełda wsparła również One River Asset Management jako partner oferujący pełny zakres usług i powiernik.

Handlowiec Scott Melker nazwał te masowe odpływy „szalenie zwyżkowymi” jako „ogromne zakupy wycofane z giełdy, bez zamiaru sprzedaży”.

BTC hat in den letzten Stunden eine starke Rallye erlebt und zum ersten Mal in seiner zehnjährigen Geschichte 30.000 US-Dollar durchbrochen . Die Königsmünze stieg dann über 31.000 USD und stieg weiter an.

Zum Zeitpunkt des Schreibens dieses Artikels notiert BTCUSD bei 32.072 USD und hat in der vergangenen Woche über 25% zugelegt

Die jüngste BTC-Rallye hat es von der Marke von 20.000 USD am 15. Dezember geschafft, in nur 17 Tagen Höchststände über 30.000 USD zu erreichen. Der Anstieg hat sich im Jahr 2021 mit Volldampf fortgesetzt und das Flaggschiff der digitalen Anlagen über ein Niveau gebracht, das seit langem von den Investoren angestrebt wird.

Der historische BTC-Lauf wurde hauptsächlich von institutionellen Käufen und vielen Wall Street-Spielern vorangetrieben , die sich endlich auf Krypto erwärmt haben. Wall Street – Firmen im Jahr 2020 $ 5750000000 in die digitale Asset – Klasse gepumpt, nach jüngsten Daten aus Krypto – Zuflüsse berichtet von CoinShares Research.

Nachdem die Bullen endlich die psychologische Barriere von 30.000 USD überschritten haben, besteht die große Wahrscheinlichkeit, dass der Schritt die Tore für die weltweit führende Krypto öffnen könnte, um eine Fortsetzung ihres parabolischen Aufwärtstrends zu sehen.

Die Hauptphase des Bitcoin-Bullen ist da, sagt Analyst

Laut dem Kryptoanalytiker Willy Woo ist hier die Hauptphase des BTC-Bullen. Der angesehene Kryptoanalytiker kam zu diesem Schluss, nachdem er die Kapitalzuflüsse in den BTC-Markt beobachtet hatte.

Der Technologieanalyst Kevin Rooke wies auf den BTC Trust (GBTC) von Grayscale Investments als eine der führenden Institutionen hin, die die laufende BTC-Rallye vorantreiben.

„Schlechte Nachrichten für BTC-Bären. Der Bitcoin Trust von Grayscale hat an einem einzigen Tag 12.319 BTC zu $ ​​GBTC hinzugefügt. Das ist mehr als die 11.512 BTC, die sie in der gesamten letzten Woche hinzugefügt haben, als BTC seine ATH gebrochen hat “, twitterte Rooke .

Darüber hinaus besteht ein starkes Interesse des Einzelhandels an der Benchmark-Kryptowährung, wie aus den PayPal-Kryptovolumina hervorgeht. Laut Pantera Capital, einem führenden Crypto-Asset-Fonds, erwirbt Paypal bereits mehr als 100% des neuen Angebots von Bitcoins. Diese starke Nachfragedynamik dürfte die Königsmünze in den kommenden Wochen und Monaten höher treiben.

DOGE-Preis explodiert höher

Dogecoin (DOGE) ist eines der leistungsstärksten Krypto-Assets des Tages, nachdem es um 50% gestiegen ist. Diese exponentielle Rallye kam, als nach Angaben von CoinGecko am vergangenen Tag Altcoin im Wert von über 700 Mio. USD gehandelt wurde.

Zum Zeitpunkt der Drucklegung ändert DOGEUSD den Handel bei 0,00865 USD, dem höchsten Preis der Münze seit der Rallye im Februar 2018.

Bitcoin’s continued strength could provide further gains until the end of the year, but a sharp downturn is also conceivable.

Crypto Trader is currently jumping from record high to record high, which leads some experts to wild speculation as to what the market-leading cryptocurrency can possibly achieve by the end of 2020. At the current walking pace, the next four days could still have one or two surprises in store.

Historic leap

Although a price jump of 8 – 9% measured against the historical volatility of Bitcoin does not seem exceptional, in 2019 there was even a jump of 42% , crypto market researcher Ryan Selkis points out that yesterday’s price jump from 2,300 US dollars Dollar is only the second time that Bitcoin has gained so much in just one day.

Carried by this euphoria, some crypto traders are already wondering when Bitcoin will be able to jump a day of 10,000 US dollars for the first time.

Hope for $ 30,000

There are now the best conditions for such a novelty, because the hashtag “#Bitcoin” trended yesterday with almost 164,000 tweets on Twitter. The second most popular hashtag in this period was clearly left behind.

As Cointelegraph has reported, the market-leading cryptocurrency is meanwhile again above the calculated average value of the Stock-To-Flow (S2F) forecast model, which outputs a price target of 100,000 US dollars. A sustained soaring is all the more likely.

At the same time, the search queries on Google are significantly lower than during the record run in 2017. According to Google Analytics, the popularity of the search term “Bitcoin” is currently less than a fifth of the previous record. The interest of the general public and private investors can currently still be expanded, which gives the price room for improvement.

70 companies registered in the Reclame HERE were contemplated. This year there was a reduction of more than 60% in the volume of complaints.

2020 was the year in which Bitcoin reached its highest value, being traded for $ 24 thousand, a price never seen in the history of digital currency .

Cryptomoeda won the spotlight of several major sites, being the asset with the highest value of the year. Despite the growing interest in the digital asset, Bitcoin-related complaints fell in 2020.
According to a survey of the Complaint HERE made for Livecoins, the number of Bitcoin-related complaints fell by 66% this year compared to 2019.
According to the data, 10,068 complaints were registered on the website this year, already in 2019, the number was 29,895. A decrease of 66.32%.

• YEAR NUMBER OF BITCOIN COMPLAINTS
• 2016 219
• 2017 7.742
• 2018 4.747
• 2019 29.895
• 2020* 10.068*

Many pyramids with Bitcoin in 2018 and 2019

In 2020, Bitcoin’s rise was motivated by institutional investors, unlike 2017, which was motivated by retail investors. After Bitcoin hit a record price in 2017, many companies emerged to try to get a share of the market, with the interest for the „novelty“, the financial pyramids and coups also emerged.

Thus, 2018 and 2019 were marked by people who believed they were investing in Bitcoin, but in fact were investing in pyramids, what followed was a rain of complaints and lawsuits.

In 2020, however, the market is more mature, according to the Complaint HERE, there was a „cleaning in the market.

„In 2020, Complaint HERE notes that the drop in the volume of complaints about bitcoins compared to 2019 was due to a cleaning up of the market. In 2018 and 2019 there was a peak of novelty in this financial transaction and with it appeared the peaks of blows given by some companies. But in 2020 this race for bitcoins was not repeated. The race in 2020 was to invest in the stock market,“ said the company in a statement sent to Livecoins.

In 2020 there were two months that had more than 1500 complaints, curiously were the months that Bitcoin began to recover from the 50% drop in March. From July, however, the complaints have diminished and returned to an average of 600 complaints per month.

More mature market

The main reason for complaints is related to delays in looting, either because the user complains that the transaction is taking too long, or simply because some company stopped paying (which is still common).

The other reasons are related to the support of the brokers, that sometimes take time to solve some problems of the customers, the market of cryptomoedas is fast, and any second can make difference, therefore, if a user has difficulty to access his account, this can mean loss, either to sell an asset at the right time, or buy another that could go up.

Among the main complaints are:

• Withdrawal
  Deposit
  Password
• Strike
  Payment
  Download
  Cancel account

Most of the items are related to the support of the companies, while Withdrawal and Deposit are related to the efficiency and seriousness of each platform.

For Reclame HERE, the companies that are still left in the market are solving customers‘ problems, with a 90% solution rate. According to the analysis, several companies that had many complaints in 2018 no longer exist.

„The analysis made of the data from the site Reclame HERE and the market behavior indicates that the high value of bitcoin in 2020 did not translate into the interest of search on the subject in general. In addition, in 2020, the rate of resolution of complaints assessed on the platform is high, up to 90%, and many companies that existed in 2018, for example, no longer exist“.

As can be seen, the market trend is to mature, eliminating companies that provide poor quality service to their customers, and also those that only appear to harm investors.

„It is worth remembering that the very low reputation of companies that operated scams or had many operational problems helped consumers to avoid problems and seek more reliable companies. With this, the consolidation of the market took place from the reputation“.

How will it be 2021?

The fall of complaints and the decrease of the term „coup“ shows that people are already smarter and probably running from coups.

However, there are some companies that are appearing with a camouflaged coup, they usually promise from 7% to 15% profit per month, infiltrate in big sites, present even programs on TV and win a certain authority to be able to deceive their investors.

There are others that buy articles sponsored in big sites but with report content: „according to company X governments are the biggest Bitcoin holders“.

Kæmpe hacking på den franske Bitcoin Ledger-mester: Tjek med det samme, hvis du er bekymret!

Afslør aldrig dine private nøgler! – Sidste juli afslørede producenten af ​​hardwaretegnebøger Ledger, at dets database havde lidt lækage af personlige data fra sine kunder. Siden Bitcoin Future da har disse samme kunder været nødt til at gennemgå forskellige phishingforsøg, hvad enten det er „klassisk“ via e-mail eller endda via SMS til dem, der havde meddelt deres telefonnummer til Ledger. Og tingene bliver desværre sandsynligvis ikke bedre.

Over en million e-mails afsløret, næsten 300.000 kunder truet

Da vi troede, at tingene ikke kunne være værre … Som rapporteret af vores kolleger fra Bitcoin.fr, har en hacker sat online – tilgængelig for alle – de private data fra Ledgers kunder.

Ifølge hackers indlæg nedenfor, offentliggjort på RaidForums:

”I dag stillede jeg Ledger.com-databasen til rådighed for dig, som du kan downloade gratis (…) Den første bekræftede [købs] pris, jeg så for denne database, var 5 BTC. (…) Nu kan du få det gratis. „

I alt, stadig ifølge hackeren, ville det være 1.075.382 e-mail-adresser og 272.853 telefonnumre og fysiske adresser, der ville være blevet afsløret. Ifølge Bitcoin.fr er 16.000 franske Ledger-kunder berørt. Ifølge Ledger, som vi kontaktede, kunne de udnyttede data vedrøre de sidste tre år.

Under alle omstændigheder er dette meget mere end tallet på 9.500 lækkede private kontaktoplysninger, som Ledger oprindeligt havde meddelt under afsløringen af ​​hacket i slutningen af ​​juli 2020. Disse kunder er dog de mest i fare siden i værste fald tilfælde, fysiske trusler eller indbrud kan forekomme, da deres postadresse er afsløret.

Ifølge Benoît Pellevoizin, VP Marketing hos Ledger, ville hackerne have udnyttet en „serviceudbyderfejl“ med ansvar for deres e-handelsmodul: sidstnævnte ville have kodet API-nøglerne til at styre disse meget følsomme filer, hårde og “I klar” i modulkoden.

Hvordan ved du, om du har lækket Ledger?

Meget lidt trøst: på grund af offentliggørelsen af ​​disse data, der er tilgængelige for alle, kan du her kontrollere, om dine er blevet stjålet eller ej. ”Har jeg været pwned” hold prøver også at e-maile kunder, når detaljer er afsløret.

Forresten kontrollerede din nuværende tjener alene og heldigvis blev kun min e-mail-adresse lækket (gudskelov, jeg havde ikke bestilt og givet resten af ​​mine kontaktoplysninger). Desuden for sådanne følsomme genstande og alt relateret til kryptokurver generelt: foretrækker leveringssteder eller professionelle adresser frem for dine personlige postadresser, når det er muligt. Nu kom jeg af med et par flere spam-e-mails, men det kunne have været værre.

CZ announces that Binance is in the process of obtaining the PSAN registration.

Actors who are not registered incur sanctions.

Changpeng Zhao aka CZ told the Paris Blockchain Week Summit (PBWS) that Binance has filed a case with the AMF to comply with regulations in France.

PSAN registration

To date, 4 French companies have obtained Bitcoin Formula registration namely Coinhouse, LGO Exchange, StackinSat and SheeldMarket . Binance would be the first entity of international stature to obtain registration.

Registration involves in particular the establishment of internal control procedures to ensure compliance with obligations such as the fight against money laundering, terrorist financing (AML-CFT) as well as the freezing of assets.

Tightening of regulation in France

Bruno Le Maire presented an ordinance on Wednesday December 9 in the Council of Ministers to strengthen the supervision of cryptocurrency purchases.

More concretely, French exchanges will have to toughen up customer knowledge processes and ask for a second proof of identity. The SEPA transfer would be the second proof envisaged by the government.

These new requirements echo the dismantling in France of a terrorist financing network using cryptocurrencies.

ADAN reacted to these new constraints for the crypto-blockchain industry in France:

On the form, this ordinance again establishes the amalgam between digital assets and the financing of terrorism. However, while digital assets can be used for illicit purposes, recent studies show that these uses are very low today, in terms of the amount and number of transactions.

Recently, more and more decentralized exchange (DEX) tokens have come onto the market. But what are currently the largest DEX tokens? The five largest decentralized exchange tokens are examined below.

In addition, the popularity of decentralized exchanges has increased dramatically in the last few months. Uniswap even overtook Coinbase in September, recording a trading volume of $ 15 billion

The main advantage of a DEX is that it does not have a central intermediary. As a result, you no longer have to hand over your assets to a central exchange, but remain in control of your cryptocurrencies. In addition, various coins can be listed on a Bitcoin Bank scam without much effort. In addition, users have more privacy, less market manipulation, sometimes better liquidity and often an accessible user interface.

However, for some trading pairs, the decentralized exchanges need to improve the depth of liquidity, accelerate the speed of order execution, and lower the fees. Even if the trading volume on the decentralized exchange decreased in October, a clear trend of steady growth can be seen.

SushiSwap (SUSHI): Market capitalization $ 67 million

SushiSwap is a fork of the Uniswap protocol . The SUSHI token grants the holder control over the decentralized exchange protocol and pays part of the collected trading fees plus the SUSHI token to the liquidity providers.

In addition, for the governance of the protocol, SUSHI token holders can submit a SushiSwap improvement proposal (SIP), which the community can vote on with SUSHI tokens.

The aim of SushiSwap is to be a further development of Uniswap. But after Uniswap has distributed its UNI token , the two DEXs are even more similar than before.

The main difference is that some key parameters such as trading fees and the amount of payouts to liquidity providers are different. SushiSwap strives for a fairer distribution of profits and also wants to give smaller investors the opportunity to provide profitable liquidity.

Están siguiendo a otros bancos centrales, incluyendo al Banco Central Europeo, para estudiar las monedas virtuales.

El banco central de Estonia, Eesti Pank, anunció el lanzamiento de un programa de investigación para estudiar cómo construir una infraestructura de moneda digital.

Según un comunicado, el Eesti Pank se asoció con las empresas tecnológicas SW7 Group y Guardtime para el proyecto de investigación. Su objetivo es ver si una solución de cadena de bloqueo de la infraestructura de firma sin llaves (KSI) puede ejecutar su programa de moneda virtual. Estonia ya utiliza la tecnología de cadenas de bloqueo de KSI para sus servicios de gobierno electrónico. El proyecto del banco también estudiará nuevas soluciones de pago „que pueden hacerse posibles mediante el uso de identificaciones electrónicas y otras soluciones de gobierno electrónico estonias“.

Sin embargo, el proyecto no especificará qué tecnologías deben utilizarse.

El proyecto constará de varias fases y tendrá una duración aproximada de dos años. En la primera fase se estudiará la manera de construir una plataforma escalable, práctica y segura que cumpla los requisitos de los fondos digitales. Al mismo tiempo, la plataforma también necesita marcar las casillas de velocidad, seguridad, privacidad y resistencia.

Rainer Olt, jefe del Departamento de Sistemas de Pago del banco, dijo:

„Como banco central pequeño, el Eesti Pank elige cuidadosamente los proyectos de desarrollo de los bancos centrales de la zona del euro a los que podemos contribuir de forma significativa. A lo largo de los años, Estonia ha desarrollado unos conocimientos técnicos únicos sobre la forma de mantener una administración electrónica segura, privada y eficiente. La singular riqueza de experiencia de Estonia proporciona un buen impulso para poner en marcha un proyecto con las empresas tecnológicas SW7 y Guardtime para explorar oportunidades tecnológicas. Esta última es el socio de cooperación a largo plazo de Estonia en la esfera de la cadena de bloques y una de las mejores del mundo en su campo“.

El banco subrayó que se esfuerzan continuamente por desarrollar el entorno financiero y su sistema de pagos para estar a la altura de los tiempos y satisfacer las necesidades de los ciudadanos.

Estonia se ha inclinado hacia la tecnología de la cadena de bloques, aunque su programa de residencia electrónica fue recientemente objeto de críticas cuando los residentes electrónicos fueron vinculados a estafas.

El mes pasado, la presidenta del Banco Central Europeo, Christine Lagarde, explicó que la adopción del euro digital no significa prescindir del decreto.

I procuratori sostengono che una donna del Nevada ha pagato 5.000 dollari a Bitcoin per l’omicidio del suo ex marito. Ma il sito era una truffa e lei è finita in prigione

Una donna avrebbe pagato l’ex marito per l’omicidio del suo ex marito con il bitcoin attraverso la rete oscura – ma il sito non era altro che un colpo di stato e le autorità hanno successivamente arrestato l’imputato.

Kristy Lynn Felkins, 36 anni, vive a Fallon, Nevada, e ha pagato 5.000 dollari a Bitcoin Revolution attraverso il sito web fasullo, che non è più attivo, pensando di poter assumere un killer a noleggio, secondo i documenti del tribunale distrettuale degli Stati Uniti per il distretto orientale della California aperti questa settimana.

Gli investigatori federali hanno arrestato Felkins quando hanno ricevuto un rapporto sul sito. Hanno rintracciato le transazioni Bitcoin della donna per trovare i messaggi incriminanti e prenderla in custodia.

La presunta trama dell’omicidio è iniziata nel 2016, dicono i documenti. Felkins ha contattato qualcuno sul sito utilizzando Tor – un browser utilizzato per accedere al web oscuro. Il sito ha informato Felkins che per nascondere la transazione, avrebbe dovuto „lavare“ Bitcoin scambiandolo con diversi fornitori attraverso LocalBitcoins.com.

Siti web profondi stanno vendendo maschere N95 e clorochina bitcoin

Secondo i documenti, Felkins sospettava che il sito potesse essere una truffa – e si è persino chiesto: „Dato che so che non siete dell’FBI, hanno la capacità di hackerare il dispositivo di qualcuno e di risalire al suo vero IP. Sono solo prudente“.

Ma Felkins ha continuato con le transazioni e ha inviato 12 Bitcoin tra il 6 marzo e il 9 marzo 2016, in modo che il suo ex marito è stato ucciso fuori dal posto di lavoro, dicono i documenti.

I documenti affermano anche che Felkins ha persino chiesto se l’omicidio potesse sembrare una „rapina andata male“ – anche se quando è stata informata che sarebbe costata 4.000 dollari in più, ha chiesto solo di procedere con il piano di qualcuno di sparare al suo ex marito.

Il sito web fraudolento ha chiesto a Felkins le ragioni dell’omicidio. Si suppone che abbia scritto: „Quest’uomo ha abusato di me mentalmente, fisicamente, sessualmente ed emotivamente“. Sono scappata via e poi mi ha portato via i miei figli. Ora abusa dei miei figli mentalmente e minaccia il loro benessere fisico. È un serpente e un maestro della manipolazione“.

Il sito web avrebbe detto a Felkins che suo marito non è stato trovato sul posto di lavoro. Quando ha chiesto la prova che avevano trovato la sua posizione, il sito web ha inviato una foto dubbia del luogo, hanno detto i documenti.

Felkins ha smesso di comunicare con il sito – che ora è chiuso – nell’aprile 2016. Le autorità sono venute a conoscenza del piano nel 2019 e hanno incriminato Felkins giovedì (24).
