Oh that's not really what I meant.
To make it quick, never sell what you bought, even if you feel you could win at that game and stack even more bitcoin by timing the market right. Chances are you'll end up rekt.
As for your DCA, idk if there really is a better way. From everything I've seen, DCAing in a daily, weekly or even biweekly bases gives results that are very similar. As long as you do it by regularly that's all that matters.
And I have a dip stash too 😉
