Actually my plan has been made long before now I just have to follow that strategy for the remaining six months or until the end of bitcoin halving. I see you have gone hardline once to make bitcoin investment although I have not gone that hardline but have been making a fixed amount every month or every week.
I won't call your strategy bad but I don't think your objective needed to be limited to double profits. If you want, you can keep your life as normal and do bitcoin investment for a long term with a certain amount of your earnings only excluding the access expensive ones. The current price of bitcoin is half of its all time high price so I think bitcoin halving in the next bull season I think it will touch its new all time high price and you have to wait for that so I would say only 2x your profit  Adopt a more long-term strategy without limiting yourself. And yes definitely do a proper dca management for risk management and then start investing.
