Bitcoin and ethereum prices have fallen sharply on Thursday, plummeting 25% on worries that crypto-currencies have entered a period of mass selling by recording technical levels that could offer great resistance to a rebound on the rise.
The decline in bitcoin comes a few days after the digital currency hit record highs at $ 3,000 on Monday.
Meanwhile, the ethereum has tumbled to $ 285.01, then rebound slightly to $ 290.74 at the start of trading in New York, leaving $ 101.16 or around 25.8%.
Investors, however, remain optimistic that ethereum will be the alternative cryptodivisa that steals the bitcoin spot as the largest and best capitalized block chain, a phenomenon known as "the flippening."
