With the Bitcoin block reward halving approaching, investors and analysts have differing opinions on its potential impact on the cryptocurrency market. Bitwise Chief Investment Officer Matt Hougan believes that history shows that Bitcoin prices have risen in the long term after halving, and that a reduction in supply and institutional investment will drive prices up. However, Dan Dolev, managing director of Mizuho Securities, expressed skepticism, believing that the market has already fully reflected the halving and warning of possible selling pressure. Jeff Hancock, CEO of Coinpass, emphasized the increasing interest of institutions in Bitcoin, but there are still differences in the market.
