On the evening of June 2, Blitzcrypto founder Azhe said that when Bitcoin could not change itself, it would definitely be eliminated. Within five years, the focus of our discussion will not be bitcoin, but more likely to be stable coins or something more interesting and self-improving. If Lightning Network is launched from 3 years ago, it may become a game changer. It may not even have Eric 20 in Ethereum. I think the lightning network is too late and has missed the best window.
