Bitcoin declined as much as 4.2 percent to $5,791 on Friday, the lowest level since November, according to Bloomberg composite prices. The cryptocurrency recovered on Saturday in Asian hours, rising 8.6 percent to $6,397 at 11:35 a.m. in Tokyo, according to Bitstamp.

Still, Bitcoin is down around 55 percent this year, according to Bitstamp. Other coins including Ether and Litecoin slumped more, while the combined value of tokens tracked by CoinMarketCap.com declined to $236 billion. At the peak of crypto-mania, they were worth about $830 billion.

Lesser-known tokens have been hit the hardest. Dead Coins lists around 800 that are effectively worth nothing, while Coinopsy puts the tally at more than 1,000. Fewer than 4 percent of coins with market caps from $50 million to $100 million were successful or promising, according to a March analysis from ICO advisory firm Satis Group.
