Bitcoin prices dropped to a low at $44,710 late on Feb. 25 before purchasing $46,500 at the main support. Before awaiting bullish continuation, analysts are looking for $50,000 to become a proven help. The premium on GBTC has fallen as low as -6% and is currently floating around -2%. Concerns about rising US Treasury yields are putting pressure on global financial markets, and cryptocurrency prices could be dragged lower as a result.
