The bottom is when...it can't go any lower. As shown by Zimbabwe and Venezeula, the bottom of fiat is zero. The ancient Greeks are all gone, but their money didn't go anywhere, hence a bottom much higher than zero. Bitcoin, on the other hand, has no such redeeming qualities, and it's bottom is the same as fiat - zero.

Offcourse This is how iT works When the mind isnt evolved with the time Where we are linving in...... When intelligence reaches the bottom, its not possible to see the more advanced and decentralized future we are entering these days
