Buddy, nothing is good in excess. The reason for saying this, is to go overconfident is being many times face a lot of losses. A person I know is similar to your activities, he himself told me that he will gain profit by doing this trading, he does both future and spot trading with dollars buying from me. But in case of selecting coin he selects alternative coins in the hope of extra profit. Ultimately it appears that he has faced loss. Moreover, there is the issue of emotion control, so some of my friends faced about 18k and another 50k dollars in the Luna incident.
But if you can follow the strategy you are currently adopting correctly, after long term strategy you can gain a good profit. Here you must be patient and control your emotions. And of course by following a proper DCA method you can invest in Bitcoin for long term. Best of luck.
