While I'll agree with JB's basic premise (and indeed yous), I'm a little unsure of where he's coming from with his "Going all in on Bitcoin". For many, DCA is the only real option. In fact, many will be DCAing without even knowing it; buying (as you say) as much as they can, as soon as they can, or as often as they can. And this will work, long term. What I try to do, with my trading, is to DCA positions; opening small value long positions as the $ price falls, and close them out as the $ price rises. This works, in a Bull Market. In a Bear Market (which I've yet to trade in), I will do the opposite and trading with short positions, but I know that this is very much more risky, as even in a Bear Market, there can be some very strong rallies, just as with a Bull Market, I see some very strong draw downs. So, rather than "Going all in..." I take the approach of not putting all of ones eggs in the one basket.
