Jason Calacanis, an early investor in Uber and Robinhood and a well-known angel investor, wrote on the X platform that Bitcoin has been monopolized by some giants, and now is the best time to build a better Bitcoin, "the game needs to be restarted". However, Jason Calacanis's views seem to have caused disagreement in the industry. Brady Swenson, a co-founder of Swan Bitcoin, said that Bitcoin is a technological revolution that changes all industries, rather than following a single technology adoption curve like the iPad. Bitcoin as a value transfer protocol will never be replaced, but the race for a second-layer protocol continues.
