I haven't really used any other method to use Bitcoin aside DCA, my mentor that introduced me to Bitcoin actually explained to me that aside DCA strategy there's lump sum and buying on the dips but I was more comfortable with DCA strategy as it's more safe and stress-free for me. With DCA strategy you can budget a little amount of money from your salary or your business and buy, I think most of Bitcoin's investors use the DCA because you can buy at any time that pleases you with any amount you can afford.
Everyone must have their own strategy in investing, both DCA and lump sum are equally good if we optimize them and can achieve one goal. The key is that we must know that point so that DCA can be more optimal, and there is still a possibility that lump sum is more optimal in our strategy. The point is, this goes back to the strategy that you master, the important thing is not to follow other people's strategies, in the end you will depend on other people.
I also like to do it with the dca strategy, because of course I invest in bitcoin for the long term and with the dca method we don't have a headache either. In addition, DCA also has many advantages compared to other strategies. However, DCA Bitcoin by only buying directly every month for me is also less effective in getting big profits. So it's better to do DCA Bitcoin by including technical analysis and looking at Bitcoin trends.
