I may not prefer using DCA as a strategy for buying Bitcoin
DCA'ing most not be for everyone but to those who are yet to take a final decision to buy at a go without having the mind of doubt that it may go dip or higher at this point such person(s) may decides involving themselves with DCA. Then if you think the price won't come down or won't dip anymore and you have the available funds to invest then buying at a go is also better because if you don't buy at that point you would end up regretting maybe you have to wait till further noticed when bitcoin price dropped to price you missed.
Lets take for instance, first week of last 2 month if someone purchased a bitcoin at a go without doing DCA don't you think such person could have made about 5 to 10 percent of their investment? Yes this is true but the person who is doing DCA may not have that profits because s/he ends up accumulating very little fraction of it.
A person should try to understand, analys and make a good decision on how and when to enter the market. At most time DCAing is favorable but still at a point where you feel that there is a current dip and entering the market at that time will give you much profit than buying in fraction, it is ideal to accumulate more and more and that point.
Sometimes you need to alter your stretegy to achieve something better, like for instance due to the current price of Bitcoin, we all know Bitcoin is start making the bull run and is not just going to go up once it might decide to still go down below $40k now seeing the market go below the current price in hands with it's volatile nature, having a lot of spare funds with you instead of you waiting for the specific interval set for DCAing, because the price might go up while waiting for the specific day to accumulate, it will be very good if a person can buy there at that price, there by giving him better percentage profit of his investment
