So, to alleviate which pains your more, or pains you less, the thought of missing out or the though you could get more, then the logical thing to do is hedge half: buy with half of what you have, and then buy DCA with the other half. That way, you only feel half the pain. And if the price is stable the whole time you were DCA'ing, then there is no pain at all either way.
Plus if it drops like a mofo, you have money to buy the dip.
If you believe the Bitcoin will always recover sooner or later (which it always has eventually but don't expect me to underwrite that for you), it's a no-brainer.
