After the US SEC (Securities and Exchanges Commission) announced that it’s starting an investigation, the stock value of Longfin (fintech firm) has dropped below 30%.

According to a report, on 2nd April, Longfin divulged the investigation in a public 10-K filing to the Securities and Exchanges Commission. Longfin is among the NASDAQ-listed fintech companies and its market cap shot-up above 1,000 percent in last December, within only 2-days.

Investigation By SEC

On 5th March, Longfin was informed by the Division of Enforcement of SEC that they will be investigating transactions in the company’s shares and also demanded the documents related to its IPO and acquisition of Ziddu.com. Ziddu.com is a firm that focuses on smart contracts and micro-lending via blockchain technology.

In the 10-K filing, Longfin showed that its aim is to cooperate with the SEC investigations. The document says:

“We are in the process of responding to this document request and will cooperate with the SEC in connection with its investigation. While the SEC is trying to determine whether there have been any violations of the federal securities laws, the investigation does not mean that the SEC has concluded that anyone has violated the law.”

What does Venkat Meenavalli have to say about it?

CEO of Longfin, Venkat Meenavalli also acknowledged this gigantic spike in stock value last December, as he stated:

“This market cap is not justified. I valued my IPO pricing at $5.” He also added:

“We are a profitable company… We have nothing to do with this euphoric mania.”

The stock value plunged really quick after an adverse tweet was posted by a well-known short-seller, Andrew Left’s Citron Research and news that the FTSE Russell was considering to eradicate Longfin from its benchmark Russell indexes due to inadequate free-floating shares.

As for the negative view of Citron, Meenavalli said:

“We are going to take legal action after we file the 10-K” and added, “The company is a profitable company, making revenue.”

Also, at the beginning of this year, the SEC reported that it’s going to start an investigation on companies that are using public enthusiasm and blockchain technology to deploy their stock prices.

Some famous names in the financial or economic industry are buying Bitcoin which is a good sign for Bitcoin.

Bill Miller is one of the renowned names in Bitcoin community. According to Forbes report on Tuesday, Bill put 1% of his net wealth into Bitcoin in the year 2014. The report reveals that the cryptocurrency is one of the top properties in Miller’s $120 million hedge fund.

Showing its image of volatility, Bitcoin fell in January 2014 from a peak of $1023. According to CoinDesk, on October 2014, it was just around $287. That’s the reason which puts the return of Miller’s Bitcoin anywhere from 126% to 707% – based on the price of Bitcoin which was $2315 on Wednesday.

Josh Brown:

The other name is Josh Brown – Chief Executive of Ritholtz Wealth Management and a CNBC contributor. In a blog post on Tuesday, Josh stated that he used Coinbase to purchase Bitcoin by a “Small Amount of Money”.

He said I think I have been through proper seasoning at this point. In case it does not drop this year after the fork, the developers argue that this could split Bitcoin. He revealed that it is going to drive mainstream among financial pros. Brown said: My main thing is, this would not go away”.

If a greater number of developers don’t favor an upgrade system for the Bitcoin, the cryptocurrency may split on 1st of August. However, a majority of Bitcoin miners have started to show their support.

Lastly, the announcements of this week follow the Standpoint Research’s Ronnie Moas. Ronnie Moas purchased a small amount of Bitcoin and thinks that it could hit $5,000 within a year.

Mike Hearn talks about Bitcoin Cash Mistakes

Want create site? Find Free WordPress Themes and plugins.

Mike Hearn, a long-time bitcoin developer, quitted the project back in 2016. However, on Thursday, he broke his silence as he openly talked about the present state of the project in Reddit Q&A session.

Mike Hearn has since joined the banking consortium startup “R3” and in the Q&A session, he discussed multiple topics, which also included the bitcoin cash hard fork and the block size discussions that eventually directed the developers to discord over the roadmap for largest cryptocurrency of the world.

Mike Hearn Remarks

Worth mentioning, the remarks of Hearn showed his own attempts to reform the bitcoin protocol, in the year 2015 whereas, 2016 initially indicated the separation. With Gavin Andresen, who was the lead developer of the bitcoin digital currency project at that time, Hearn presented a software to advance the block size, offering a hard fork that was rejected. However, Hearn quit the core team after that, writing that the cryptocurrency, bitcoin has failed because of problems with its community.

Though at this time, Hearn thinks that the bitcoin cash has gotten many of the original problems of the project as he wrote:

“Bitcoin cash strongly resembles the bitcoin community of 2014. This is not good.”

Views About Bitcoin Cash

Hearn declared his views about the bitcoin cash, how it’s repeating the Bitcoin mistakes. For him, Bitcoin Cash lacks dignified governance, just like Bitcoin did back in 2014 and often communicates through Reddit, where according to him, users are able to censor ostracized opinions.  Intrinsically, he notified the users of bitcoin cash to find an alternate platform where moderator control would be restricted and the views of the community on the upcoming advancements could be appropriately measured. He particularly expressed fear that bitcoin cash was considering to hard fork its chain without any attempt to assess support. However, he still needs the community to be audacious.

He concluded by saying:

“Liberate yourselves from just proceeding along the path Satoshi imagined and be willing to think radical, even heretical thoughts.”
