Depending on each person's income and circumstances, we will have different investment plans in bitcoin. So, I have no opinion on your plan because only you know what is best for you. But investing and accumulating bitcoin is not as simple as many people think, so I hope you will continue to learn every day to have a deeper look at bitcoin and have stronger faith in bitcoin. There will be many challenges waiting for you, I hope you can maintain your plan as long as possible.
I like OP's plan but you're right, it's great that we prepare a perfect plan but whether we can complete it is another matter. There is no success without trade-offs or we have to pay a high price, and reality is much harsher than we imagine. So I hope OP will maintain his monthly DCA plan with discipline and if there are any setbacks, he doesn't give up. Bitcoin is truly an asset, a potential investment, but whether it brings us profit or not is up to us to decide, bitcoin cannot decide for us.
Everyone says that holding bitcoins is quite easy, that is only true if we compare it with bitcoin trading, but it is not easy, especially for newbies. If we lack knowledge and are steadfast with our plans, dumping when the market is flooded with Fuds is inevitable. So I hope OP tries harder to fully pursue his plan. No success can be achieved easily even if we start with bitcoin. You are right, bitcoin is a potential asset but success or failure depends entirely on us, not bitcoin.
