I agree- DCA protects you from paying a too expensive price at the cost of also not getting a "too cheap" price. But if you have an invenstment horizont of 1 year+ then you probably already think that the current price is "too cheap", so why sabotage these profits by DCAing?

Of course it could turn out other than expected, but if you don't assume that there will be geometric growth in price then a long term investment in bitcoin makes no sense anyway (too risky then).

What Risto showed that it is way more likely to miss huge profits by not DCAing.
