Most people say btc will hit 20k again mostly because that was about what the previous all time high was.

Actually, if you crunch the numbers and look at how high and fast btc can go during huge bull runs, we are looking at more like 25k to 30k.

The market has been crashing for this entire year and the past month has seen stability.
BTC tried to go below 6000, and it did for a tiny bit then went right back up over 6000.
This really shows that the market isn't willing to let it drop that low yet.

For the past 2 years, Nov/dec has always show btc pumping hard.
There is no reason to expect that it won't this year.

But you really do need to understand, that the higher and faster it goes, the more crazy the crash will be.
Time everything out wisely.
