I have experience with this. I was following the DCA strategy for a few months and I accumulated a good amount, but in the end I was forced to sell a large portion of this amount due to some difficult financial circumstances. It is true that I made some profits in the sale, but I sold much less than my target.
Don't you think the problem is that you invested most of your money into a long term asset, if you do it this way, you'd frequently be forced to sell when you do not want to, that's why i have said in this thread already, that i recommend keeping part of your funds in liquid assets that you can easily convert to cash.
Take note as well that BTC isn't the only thing you can invest in for the long term, there are other assets you can diversify into. Finally, even if fiat is inflationary, you should also have some money in your bank account for quick spending.
