Basically nothing. Gokhshtein is just a dude on Twitter that has a huge number of followers; and combine that with the fact that price predictions almost always gets a lot of traction from the newbies, here we are talking about him, which is most probably his main goal in the first place.
Now he's known already since he is been featured on this thread and basically I really don't know that guy until OP mentioned his name about what his price prediction on future, and its so easy to drop some numbers maybe he just read the price history and predict that his prediction will happen. And $80k is not far figure so if this came then for sure he will claim it that he is right about what will happen to it on future and also for he want a good credits for his name by dropping his predictions .
