Now, when this is booming and big, regret always comes at the end, because if it's at the beginning, it's called registration.
You do not need to regret anything, bitcoin will still continue to increase. It is not too late to invest at all. You can start DCA or you can wait till the right time when the market fall more and invest but I will prefer DCA or averaging instead as the price fall more. Bitcoin still have a lot of potential
toshowing that its price will still increase and you can still see little profit and
it is a good hedge against inflation
