Its too early to say that Bitcoin will disappear. Actually, it is unlikely that such a moment will come when it can be said that Bitcoin has no future. This is about the same as the Windows operating system. Compared to the current system of WIndows 10, it seems that Windows XP or Windows 98 is all the more inefficient, but Windows has not died, only the number has changed, but Windows has remained the same Windows, even the start menu remains exactly like that same as twenty years ago.
