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
Of course, the best time to invest in the crypto market is when there is bearish season. However, there is no rule that prohibits one from buying even at its ATH, so most likely people will definitely buy using their hard-earned money as long as their mindset is that bitcoin price will certainly rise more in the next months or years. And as you’ve said, their money, their rules. And I’m not against in it, investing in bitcoin even at its ATH simply proves that you have a huge faith for bitcoin that it’s price will continue to grow despite how highly volatile it is. And as long as you are investing for long term, you can still maximize your profits when you only sell when your price goal will be achieved.
It doesn’t necessarily prove that the investor has faith. Out of the people who have invested at ATH, a handful of them are people investing out of FOMO. They don’t really believe, they are just scared that they will be filled with regret if the rocket actually leaves the sky as people hype it. But those who are really long term investors are safe. As long as they are committed to it and don’t eventually have weak hands.
