A resurgence in retail trading has driven the recent rise in Bitcoin prices to highs of around $52,000, according to Bloomberg. However, the current rally may be fading, with Bitcoin down about 1.8% this week as of 2:15 p.m. New York time on Friday. If the trend continues, it will be Bitcoin's first negative week since late January. Retail investors' enthusiasm for the recently approved spot Bitcoin exchange-traded fund and the next halving event (which cuts the supply of newly mined Bitcoins in half) has driven the asset's price up 25% in recent weeks. "Bitcoin bulls are taking a breather after four consecutive weeks of gains. A round of profit-taking is to be expected after such a strong rally," said the strategist.
