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.
I and other people or maybe we never know that in a free market that carries out long-term or daily activities there are traders who have all of that. Therefore it is no longer a secret if before starting trading activities in the free market, knowledge is the main capital before putting forward a budget because regarding coin trading the trial and error pattern does not apply like in other fields.
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.
Without thinking long, unprepared for everything that has to do with a strategy to make a profit, it's better not to become a trader or investor than to lose money.
