maybe.. but not because bitcoin will not increase in price but because they could have maximized their profits by waiting and buying bitcoin when the price is going down bitcoin will still increase in price for the next following months and its “peak” would be nothing compared to bitcoin’s price right after halving
it’s their money in the end so if they feel they can do and invest their money no matter how high the price is then good for them
Well, some of those who are buying right now are those who are new to it, so they never really had an opportunity to buy lower and I don't think they would wait for the next bear market to make their purchases so they don't really have a choice. However, some are those who didn't buy when Bitcoin was lower because they thought it will go even lower than that, and they are buying now because they have got the impression that it isn't going to $10k anymore.
You can blame the second category of buyers who are buying right now because they had the opportunity to do that earlier but they didn't because of their ignorance or maybe because of lack of experience and knowledge.
