Honestly I do not want to imagine what would have happened if there was no halving happened this year. At the same time, bitcoin got its own believers who keep on buying at every dips hence even there was no halving bitcoin might have survived like how it has done in last 2 to 3 months of times but I must say we all might have got more panic than how we reacted when bitcoin was dumped below $4k levels in the matter of 2 sessions.
When considering how FOMO will work in bitcoin space, I guess $250k will be possible in 18 months of time but for that we need new investors and world economy to be into normal. With pandemic is still persisting, I guess thinking about FOMO influenced bull run is not at all making any sense.
Hmmm... I think that these should be some very large investors - at such a price, the capitalization of bitcoin will exceed a trillion. And the pressure on the price will be huge as many early investors decide to take profits.
