You will also find people who were crazy to buy when Bitcoin was at ATH. But now that the market is giving them a chance to buy at a lower price, they are waiting to buy at a lower price. They don't really want to know about Bitcoin and they don't want to think about the bright future of Bitcoin.
You never know where is the top and where is the bottom. The best course of action is DCA. Whenever you have money for shopping buy bitcoin. Accumulate as much as possible without worrying about the price. But if the price drops significantly then push your buying habit and rest of the time just practice the regular buying habit.
For example, a bitcoin nerd would still buy bitcoin when the price was $60K up but not pushing it hard, over $100k is fine or even more does not matter. But when price dropped to $40k, he will push a little hard to buy more than usually he does. When price is dropping more and at this stage when its under $22k he gives his best. However when price drops further he collects more money (however it's possible) and buy even more! Always have a spreadsheet to know your average price. After few years when you think you have enough of it and the price is obviously above your average price, enjoy your vacation. Life is very simple.
Depositing money in the bank is not going to make your rich, the inflation rate will eat up your gains.
