Only Doraemon has a time machine, but it's just a cartoon to remind you that time cannot be turned back nor should it be wasted.
and don't let your words be repeated in the next few years, and if you feel sorry that you missed the best time at that time, don't waste it anymore. Do it decisively before the bitcoin price goes much higher and you repeat the mistake again. And you can do that with DCA to buy as many bitcoins as you can regularly at a set time, and use the money you don't need and do it for the long term until bitcoin reaches a very high price and you can enjoy it with pleasure.
and it's never too late, and I don't believe the statement that it's too late to start buying bitcoins, and that is so wrong. Because bitcoin has been proven many times to overcome all the obstacles it faces and even though there is a decline, in the end it rises again even higher than the previous price.
