Bitcoin dropped Thursday, bringing losses for the week so far to about 17 percent.
The largest digital currency by market capitalization fell 7.6 percent to a low of $7,331.52 before recovering to near $7,400, according to CoinDesk’s Bitcoin price index. That brought the quarter-to-date decline to more than 45 percent.
Ethereum, the second largest cryptocurrency by market cap, declined 9.8 percent to near $402, its lowest since Nov. 30, according to CoinMarketCap. At that price, ethereum was down roughly 25 percent for the week and nearly 47 percent for the quarter.

Information technology has fallen more than 4 percent in March as the third-worst performing sector in the S&P 500. Tech stocks led market gains Thursday morning.
