Mizuho Securities and other investment firms have reduced their price targets for Coinbase (COIN) and MicroStrategy (MSTR) following a decline in Bitcoin's value. Mizuho analysts cut Coinbase's target by 39.3% to $170 and MicroStrategy's by 20.6% to $320. This move reflects a cautious outlook on the crypto sector as Bitcoin struggles to recover after falling below $70,000. Other firms, including Benchmark, Canaccord, Piper Sandler, JPMorgan, and Needham, have also lowered their targets for Coinbase, with COIN currently trading at $164.32, down 34% over the past month. Despite these revisions, some analysts maintain a buy rating for Coinbase, citing its diversified revenue streams and strong fundamentals. MicroStrategy continues its Bitcoin accumulation, recently purchasing 2,486 BTC, despite sitting on unrealized losses.
