What you say is what should be done by all who really want to invest but do not have enough capital. For that, it can be done like what you say, namely by way of the DCA method, where in the long term it will be able to get the maximum value at once, Waiting for the arrival of the bullish season so that when we have a lot we can let go.
I think, of course, this is an idea that must be done if we want to succeed and succeed with small capital.
Typically, DCA is carried out by allocating a portion of monthly income to buy BTC for the long term. This process requires a strong belief and a stable income, only then can investors tolerate temporary losses and overcome fear to accumulate a lot of BTC at the bottom.
Investors will also learn how to allocate and manage capital effectively throughout the DCA process. I think this is even more important than their ability to accurately predict the market, because capital management planning and psychological control will be valuable throughout a financial investment career.
