Good point. It doesn't really matter what strategy a person is using; as long as they are making a profit from it, it's good. Doing DCA is good, and it allows people to invest in Bitcoin without worrying about its current price compared to their investment amount, but even if someone doesn't want to specifically use the DCA method, they are free to do that, but they need to make sure that they are using a strategy that gets them some profit, either in the short or long term.

Some people say it's more difficult to get short-term profits from Bitcoin, but I disagree. Whether you are doing spot or futures, you can always get profit from Bitcoin and its small dips as long as you can time your trades well. By timing the trades well, I don't mean that you should be buying at the bottom and selling at the top because that isn't logically possible at all times, but you should at least understand which way the market is going to move next, so that your trades gets you some profit even if you sell it within the same day.

Scalpers earn profit using that simple strategy of buying low and selling high.
