The price of bitcoin has plunged almost 25 percent since hitting a two-and-a-half year high last week amid problems at a key exchange and diminishing fears of a Brexit.
Bitcoin was trading around $590.53 by midday London time, a fall of around 23.8 percent from the $774.94 close on June 17, which marked the highest close since November 22, 2013.
The initial rise in the price of the cryptocurrency came last week as traders prepared for a process known as "halving" where the rewards offered to bitcoin miners fall, thus tightening the supply of the digital currency. With anticipation of less supply, prices spiked.
