I think the reason why people investing in Bitcoin is to earn profit where some are afraid that they will miss the chance to earn profit. You can say that it is very much like FUD or FOMO that they also want to invest. If they really want to invest then they should have bought Bitcoin when it didn't reach the price of bitcoin today.
Yes, the main reason why people continue to invest even in ATH is due to FOMO, and they also believe that the price would continue to increase.
But nobody knows how high it could reach and how the price would move, it could continue to go up or it could go down and have a price correction.
Oh so they invested in bitcoin during ATH because of FOMO is there any other reason why they did this?
Do they have no knowledge about it?
I don't think they have any knowledge, most people are still scared of the bear without knowing its the right time to invest in bitcoin, FOMO I'd just the feeling, no one wants to miss out but your here at such a wrong time, we could as well be at the peak of the bull and your just coming.
But it's not too late I guess, although it's been quite since Monday, bitcoin still have enough power to break into 100k
Maybe after the halving.
