Where will be the BTC Bottom?

It's been roughly a bear market for a while now, and where will be the bottom is a hot topic these days. In my opinion, BTC has still room to drop until the real capitulation happens; therefore I can imagine a classic 80% Drop from its all-time high which is arguably in confluence with some powerful levels, including two long time frame Fib levels.
Of course, in the end, the market will surprise us all.
