It's never just one thing. It's a bunch of things that have been kept dormant for a couple of years with the price not moving too much. Price will explode again due to built-up hype and FOMO, and then a year later it will be in free fall again and all the "smart people" will claim it will go to zero and be worthless....just like the last 20 times it did that. And on and on we go.
