Lump Sum and DCA are fine to do regardless of which one they prefer the most. In fact both strategies will only be profitable if they are actually executed at the right time. DCA at any price is fine mainly because of their approach to accumulation, but Lump Sum on dip is also fine. In my opinion, both strategies are mutually beneficial rather than finding out which one is the best between the two, but of course this must be adjusted to market conditions and also the budget we have.
The fact is that both strategies "Lump sum and DCA" are the best investment strategies, I don't do lump sum only rely on DCA strategy this is more what I prefer than lump sun there is a reason why it should be DCA because this has become the right fit for me so DCA every week at any price will not be a problem until it will still be profitable.
Waiting for the discount price I think many people do this they want to buy at once so that the results obtained at the price that the decline, maybe from them have prepared funds to do this because for myself every time there is more money holding for bitcoin it will immediately buy bitcoin without thinking about the price, yes this is called DCA.
