Bitcoin performance in the last 24 hours
Multiple virtual currencies have dropped significantly as regulators voiced concerns about them and worries grew over suggestions that the price of bitcoin has been propped up by popular exchange Bitfinex.
On Wednesday, Indian Finance Minister Arun Jaitley warned against criminal activity associated with cryptocurrencies, and said that India would "eliminate" the use of cryptocurrencies in "illegitimate activities."
A number of critics have railed against cryptocurrencies like bitcoin, citing extreme price swings and worries of dubious activities associated with the crypto world, such as money laundering.
Notably, J. P. Morgan Chief Executive Jamie Dimon called the world's largest cryptocurrency, bitcoin, a "fraud," and said that he thought it would eventually "blow up."
Meanwhile, Berkshire Hathaway Chief Executive Warren Buffett told CNBC last month that cryptocurrencies were likely to "come to a bad ending."
Cryptocurrencies are decentralized, virtual currencies that are not backed by governments. They are underpinned by distributed ledger networks called blockchains, which maintain a continuously growing log of transactions across a network of computers.
Bitfinex, Tether reportedly subpoenaed
The New York Times reported that an increasing number of cryptocurrency investors were concerned about the price of bitcoin other virtual assets being propped up by Bitfinex, one of the exchanges included in CoinDesk's Bitcoin Price Index. Tether had no comment to CNBC on the report.
Both Bitfinex and Tether, the digital currency backed by the former's executives, have been surrounded in controversy following the report. Tether — which is pegged to the U.S. dollar — was down almost 1.9 percent on Friday.
Bloomberg reported separately that Bitfinex and Tether had been subpoenaed by U.S. regulators. Alhough Tether's digital tokens are meant to be backed by U.S. dollars held in reserve, the company not yet proven so, the report said.
"The real question is whether Bitfinex has been keeping a 1-1 reserve," Charles Hayter, chief executive of digital currency comparison service CryptoCompare, told CNBC by email.
Hayter pointed out a "strange" rush of investors into a digital coin called Digix, which claims to let cryptocurrency traders invest in gold — traditionally thought of as a safe haven commodity — via its blockchain network.
"The jury is still out and fear is gripping the markets with people preferring to step out and flight to safety rather than keep risk on," Hayter said.
Hayter added in a phone interview that Friday's downward activity was likely an "overreaction" to news in the cryptocurrency market, describing such slides in prices as "common."
Mati Greenspan, senior market analyst at social trading network eToro, said that neither regulatory signals or worries of price manipulation were a cause for "systemic change" in the cryptocurrency market.
"We're coming up on support now at around $8,000, a level we've been watching over the last two weeks," he told CNBC in an email. "A light break of that is a good sign but if the break is violent it could take us lower."
Greenspan added: "Even if we go as low as $5000, it will still be double the prices that were traded in June and July of 2017."
