This obsessional idea of bitcoin becoming the global currency is baffling. Bitcoin doesn't aim to replace every traditional currency, it's more like a superior flexibility.

But do you see people go crazy for eth just like what they do for bitcoin? Accept it or not, bitcoin is the king and the king will rule
