I agree with you that buying now is a good thing to do and it can become profitable. But I will prefer to advice people to DCA instead of buying at once. I advice some people to DCA in a a way that if bitcoin fall to a price, that they should buy more. They have been doing it since bitcoin fall to $90000. It is something that has been set on the exchange as limit order. DCA is a good thing to do.
it might not only be DCA but they will need to deploy the three strategy which includes buying the dip, DCA and lump sum. provided they have the fund readily available to invest from their discretion. most time when people may have an extra cash that may be gotten from a business deal or bonus gotten as a reward or a huge amount won from gambling can be used to lump sum at a go while the fund gotten from maybe salary or from investment should be used for buying the Dip and also DCA so suely the whole buying strategy is relevant and important to deploy to get a better result.
