The well-known cryptocurrency skeptic Nouriel Roubini ("Dr.DOOM") said that cryptocurrency exchanges "are directly involved in criminal activity," especially he singled out the BitMEX platform.

Bank of England Chairman Mark Carney stressed that society needs to recognize the problems that Facebook is trying to solve with the help of the Libra project.

"It's way too expensive to do domestic payments. It's way too slow, and that hurts consumers and businesses. It stifles innovation, and it's far too expensive to send money cross-border, and there are huge financial inclusion issues related to that and costs related to that. So, while we are trying to address all these issues, we have to absolutely acknowledge the problem that they're trying to solve. And if it's not this, we'd better have some answers for what else it is," Carney said at a press conference.

Facebook founder and CEO Mark Zuckerberg tried to dispel some public doubts that have arisen about Libra's cryptocurrency project being developed by the company.

"No company is able to create a sought-after financial system. Therefore, we only laid the foundation and hope that by the time the Libra project is launched, our association will bring together 100 co-founders, among which we will have only one vote," said Mark Zuckerberg.

Jim Reid, a top manager at Deutsche Bank, the largest bank in Germany, said that the US Central Bank reduced the refinancing rate one of the reasons for the rise in Bitcoin.

"If central banks are gonna be this aggressive, then alternative currencies do start to become a bit more attractive," said Deutsche Bank's global fundamental credit strategy head in an interview with CNBC.

Jesse Powell, general director of the Kraken cryptocurrency exchange, is extremely optimistic about the further increase in the price of Bitcoin.

"When I hear people talking about a Bitcoin "correction" I'm thinking $100k, maybe $1m. That's what's correct," he writes on his Twitter account.

The US Senate Committee on Banking, Housing and Urban Affairs on July 16 will hold a hearing on the new Libra cryptocurrency being developed by Facebook.

A hearing entitled "Examining Facebook's Proposed Digital Currency and Data Privacy Considerations" was scheduled after calls from members of Congress to study the Libra project and its potential risks more carefully. There were even calls to stop the work on the project before the hearing.

Cryptocurrency analyst and BlockTV reporter Joe Saz believes that after the elimination of short positions on Bitcoin by $ 100 million, the growth of the first cryptocurrency can not be stopped.

"I think that this can keep going. There's nothing stopping it. I don't want to go too far into the clouds here, but there might have even been $100 million plus dollars in liquidations overnight…

I saw a lot of $10 million in short liquidations. So what does that mean? It means a lot of people were betting that we were headed down and they got completely smashed in the face. So I don't recommend to enter any short or long positions," the analyst emphasized. 

The chairman of the US Securities and Exchange Commission (SEC), Jay Clayton, spoke about what needs to be done in the cryptocurrency industry before approving applications for a Bitcoin ETF.

According to Clayton, the industry is in dire need of high-end custodial solutions that would be approved by US regulators. In addition, you must ensure that there is no market manipulation.

Bitcoin analyst Oliver Isaacs expressed the opinion that the first cryptocurrency rate would reach $ 25,000 by the end of 2019.

"There are multiple drivers behind the recent resurgence. There are geopolitical, technological and regulatory drivers. The net effect of the trade war between the U.S. and China has led to the sudden interest in bitcoin as a hedge on investments," Isaacs said.

Several sources close to Chinese business circles reported that the co-founder and former director of mining giant Bitmain Jihan Wu was preparing to launch a new company called Matrix.

Interestingly, the main client of Matrix will be Wu's former brainchild - Bitmain. Of course, now the new business is negotiating with other companies around the world. Matrix expected to offer custody and credit services, so the choice of Bitmain as a key client is quite reasonable. The mining giant generates a large amount of cryptocurrency that needs to be stored somewhere.
