🌐 Hackers hacked Blockfolio service to publish offensive content
Hackers hacked into the FTX cryptocurrency portfolio management service Blockfolio. Attackers sent out abusive messages to users.
A message appeared on the service's Twitter that the Blockfolio team is apologizing for the offensive content and is already investigating the issue. Users' assets remained safe and the trading platform is working fine.
“Hello, we are announcing the end of service for all black users and the confiscation of their funds. We recommend that you withdraw your money before it is lost, ”the hackers wrote in the mailing list.
FTX CEO Sam Bankman-Fried said that hackers were able to gain access to Blockfolio's signal and news streams, while other services of the company remained unaffected.
“Over the next month, I will be conducting a security audit on older non-trading portions of Blockfolio to bring them up to FTX standards. We will give $ 10 to every Blockfolio trading user and those who sign up during this week, ” wrote FTX CEO.
The cryptocurrency derivatives exchange bought out Blockfolio in August last year. The deal was worth $ 150 million.

🌐 Yearn.Finance restored the yDAI repository to work
Yearn.Finance's decentralized finance project was hacked on February 5, resulting in a hacker stealing $ 11 million from the yDAI vault. Today the project team has restored the work of the repository.
As previously reported , the hacker used multi-stage transactions and instant loans to generate a profit of $ 2.8 million. Today, the Yearn.Finance team announced the launch of the vault:
“YDAI has been restored! Yearn opened the Maker vault and released YFI tokens for a full launch. "
Yearn.Finance representatives stressed that although this time the losses of users were reimbursed by the project, next time this will not happen again and users should insure their funds locked in vaults.
To restore yDAI to work, the developers moved 1,591 YFI from their backup storage. The tokens were used as collateral for the creation of the $ 9.69 million DAI stablecoins.
Recall that on February 8, the developers of the DeFi Curve protocol announced the discovery of a vulnerability affecting the new yVault2 pool, in which Yearn Finance participates. After that, access to the pool was terminated.

🌐 The Block: Outdated Mining Hardware Gained More Popularity Amid Market Growth
The shortage of the latest generation ASIC miners on the market is no secret to anyone. However, according to analysts from The Block, with the rise in the bitcoin rate, even outdated devices are becoming more popular.
Analysts at The Block noted a noticeable increase in demand for miners of previous generations. Mining equipment sellers are increasingly offering Antminer S9 and Avalon 851 models, and their prices range from $ 80 to $ 130 per unit. Moreover, in October 2020, after the rainy season in the Chinese province of Sichuan, such devices were sold for less than $ 50 per unit.
In addition, some mining companies have begun looking for premises to house farms, assembled from outdated equipment. For example, the Chinese company Hashage is looking for a location to host Antminer S9 devices with a total capacity of 20 MW. With the growth of the bitcoin rate, the profitability of mining has grown significantly - the profit ratio for terahash reached the levels of September 2019.
Recall that a month ago, after the next recalculation, the difficulty of bitcoin mining immediately increased by 10.79%. With the current difficulty of bitcoin mining, Antminer S9 devices make a profit when the BTC rate is above $ 16,500. And at the current rates of the first cryptocurrency, the devices "beat off" in just a few weeks and then make a profit.

🌐 At the end of last year, the largest batch of ASIC miners was imported to Russia
At the end of 2020, the largest batch of ASIC miners was imported to Russia - 20,000 units (14 trucks) for a client of BitRiver.
The total power consumption of the equipment is 70 MW, and its cost is from $ 40 million to $ 60 million. The CEO of BitRiver Igor Runets did not disclose the name of the client who bought such a large batch of miners, but said that a separate Tier-III data center was launched for it on BitRiver site in Bratsk.
The equipment was supplied by "one of the countries of Asia". Of course, we are talking about China, but Runets also does not disclose the miner model. Most likely, we are talking about the latest generation Bitmain or MicroBT devices. The head of the Six-Nines data center (Sweden) Sergey Troshin noted that the hash rate of imported equipment can reach 1.1% of the total hash rate of Bitcoin.
This year, one should not expect such a volume of ASIC miners to Russia. This is due to a shortage of electronic components on the market, including a shortage of mining chips. The import of such lots into Russia in the near future is also associated with regulatory risks - the law on digital financial assets , which came into force on January 1, 2021, almost does not regulate mining activities.
In November, En + and BitRiver agreed to create a data center in Bratsk for mining with a capacity of up to 40 MW. Perhaps it was En + that imported a large batch of devices for mining .

🌐 The number of transactions in the Bitcoin mempool reaches 125,000
As usual when BTC is growing, the number of unconfirmed transactions in the Bitcoin mempool has increased and reached 125,000.
Now the volume of unconfirmed transactions is 149 MB - enough to completely fill the next 107 mined blocks. The last time a large number of unconfirmed transactions on the Bitcoin network was recorded on December 17, 2020 - then their number exceeded 143,000.
Along with the increase in the number of transactions, so too are the confirmation fees, which is the reason for the statements from the critics of digital assets. One of the users of the social network Twitter noted :
“Over the past three months, the average bitcoin transaction fee has varied from $ 2.18 to $ 17.20. Buying coffee with bitcoins is very expensive. "
The last time the Bitcoin mempool was completely cleared was on January 1 this year. According to mempool.observer , it is now recommended to set a fee of 93 satoshi per byte of a transaction so that it quickly gets into the block. Given that the average transaction size is 224 bytes, the transaction fee is $ 9.69.
On February 8, the total transaction fees received by the miners of the first cryptocurrency amounted to 84.72 BTC ($ 2.05 million). Note that Bitcoin miners in January of this year received $ 1.09 billion in profit from transaction confirmation fees - this is the highest figure since December 2017.

🌐 Litecoin founder: "companies will start buying bitcoin after Tesla"
Litecoin founder Charlie Lee believes that buying Tesla's bitcoins will revolutionize the US financial system, and many companies will follow Tesla's example.
Elon Musk's company recently bought bitcoins worth $ 1.5 billion. Moreover, Tesla plans to accept payments in cryptocurrencies. However, the car manufacturer said it would not be able to convert the received bitcoins into fiat currency. Lee drew attention to the importance of this statement. According to Lee, when sellers start accepting bitcoins without further selling or converting them, society will begin to abandon the conventional money system. Thus, a circular economy will be formed in which sellers will accept cryptocurrency, make settlements with it, and even use it to pay salaries.
“This is a turning point. One of the richest people in the world believed in Bitcoin and invested 7% of his funds in it. Now thousands of companies will follow Elon Musk. They will have confidence in their actions by seeing how Tesla does it, ”said the founder of Litecoin.
Information Tesla investing in Bitcoin provoked an increase in the first above $ 48 cryptocurrency 000.Teper BTC course corrected, and it is trading at around $ 46 500. On the growth of Bitcoin is also influenced by Twitter CEO Jack Dorsey (Jack Dorsey), running on Bitcoins assembly last week. Dorsey is convinced that Bitcoin will dominate the financial system in the future. The interest of ordinary users and corporations in bitcoin is also due to the integration of cryptocurrencies into the PayPal payment system, since bitcoin trading on this platform is becoming more and more popular.
In 2019, Lee said that the bitcoin rate will reach $ 20,000 within three years. His forecast came true, and even exceeded expectations. In December 2020, Bitcoin confidently crossed this important level, continuing to strive upward.
