DCA method is more appropriate in investing in bitcoin than some shitcoins, is obvious and I also speak base on experience. Started in this space as a spot trader, trading different coins . Was doing fine at first making some good profit because I was using spot and there's no chance for me to get liquidated (doesn't mean your funds can get hook), till a coin came out with a promising value , with alot of hyped how their project is nice and all that so was convinced to purchased it , and at first was going well because I was actually holding it then it dip , I bought the dip. Then I decided to be buying with certain amount for sometime so that anytime the price bounce back I would be in big profits , but it kept on dipping, and my losses was getting out of hand due to the DCA method I use which gave me alot of quantity. At the end it endup selling in loss , losing huge amount of money that left a mark . Now as am talking to you that coin have not even gain it self back even during this recent bill run , as coins are increasing in value . That coin still down , and I learned through experience. Don't use other coin to compare bitcoin . There's reason why all other coins are altcoins Except bitcoin.
Of course DCA makes it easier for us to accumulate Bitcoin gradually, where we can manage our financial flows and arrange everything well in long-term investment planning. Just like you, I am also new to DCA or the investment I have made has only been running for 1 year and I have found the comfort I get in accumulating Bitcoin. Apart from that, if it is in the initial accumulation phase, it is better to apply DCA and buy regularly every week to ensure our stage for the long term.
Large investors prefer to accumulate Bitcoin with DCA rather than buying all at once, moreover their budget is large enough that regular purchases with DCA will give them the opportunity to find cheaper prices in Bullish like this. However, everyone can use DCA in their investments and it all depends on the strategy they apply.
