Sometimes many people misunderstand Bitcoin when the price is dropping. Even though the way to understand Bitcoin is quite easy by carrying out simple actions without having to get too bothered by excessive circumstances.
In my opinion, DCA is still very powerful to implement.
I don't think it's that simple. You know that in the free market you can never find a trader who has the same skill, knowledge and experience about bitcoin. You will surely find them panicking when the market corrects or you may find them increasing their selling interest when the price increases. Look at how easily the market changes even when the price is trying to recover, but of course it is influenced not only by retail traders but also by some other big traders and investors.
DCA, of course, that is the recommended strategy. In practice you need a budget, but I really doubt that anyone can implement such a strategy in their investment plan consistently, unless your budgetary resources are really strong. Even I will never have consistency about DCA, it is influenced by my income and expenses every month.
