DCA method is not the only way to become successful with your Bitcoin investment and I doubt everyone that's accumulating Bitcoin is doing so through the DCA methord. Everyone has the way he gets his fund and this plays a big role in determining the methord he uses in his accumulation. Let's say you hit a project that's worth $200k and decides to invest $150k into Bitcoin and the rest of the money goes into a business that will keep you going for the period you hold on to your Bitcoin investments. Does it mean that if you refused accumulating more with the use of the DCA methord you won't be successful? Not at all. Different Individuals applies different methord to buy Bitcoin but the target is all centered at making profit and becoming successful with your investment and whichever methord you choose to use, as long as you're able to accumulate more using that methord, you will still become successful with it.
