It has been a very long 15 years ++ for me, but I cannot deny it was made surprisingly better just because I DCA in BTC (as I said above, it already deleted a chunk of interest, and deleted about 5 years from my end date). It was another headache to be honest and when I first started honestly I was scared it wouldn't pay off, but it has already so I make my peace that I will always DCA up to a point, and then calculate how much it helps me in my position to pay off my debt.
I'm glad you understand, and we cannot advice anyone on debt, I'm always trying to balance... like you said, if I stick to BTC DCA and hodl forever, I can predict a very good future to pay off a lump sum, but I'm just feeling more freedom to be getting the debt payment down to a level that is not so scary as it was 10 years ago.

That's why I just stick to new ATH, sort of. It makes my job easy because DCA means every single time you kept BTC is lower than the new ATH, and on average you make a lot more, than if you saved 4 years on bank interest (I use a fund, it's slightly higher than bank interest but it also comes with risk of small loss as most of it is protected by deposit guarantee).
The thing about debt, especially business and personal loans. You can get a semi low interest annually, but if you missed a payment or became unable to pay like I did then they strip away everything, at a bad price. I won't go into details but I lost everything I had, and then they finalized the debt into 1 single amount with a long repayment scheme. But you first pay the interest, then the principal. And the longer you take to pay, the more the principal accrues interest. So shaving off the years helps a lot with compounding. In my case, because I made many mistakes in the past, and the system punishes you even more, what started out as manageable interest became heavy! I can say it is more than 10% per year if you take into account all the extra costs (like paying late, or paying the insurance for the debt).
Last year's near 100k wave was definitely not so good, but take into account the pre 40k buys from early 2024, I practically 2.5x that. Again, very difficult to predict and catch waves, and I could make it more efficient but this problem of repayment and debt servicing, forces me to try be conservative. And it worked out so far. The plan is to continue another 2 ATHs... by then I am very very hopeful to reach a repayment milestone that grants me back some freedoms. Such as getting a passport to travel, opening another bank account, getting a credit card.
Financial prison is so bad you just want to get out of it asap...
Thank you for all that. It made me think

It sounds like you are mostly chipping away, and so it is good if you found something that you believe to be mostly working for you and your situation, especially since once earlier mistakes were made, then you are left to deal with such mistakes as best as you can under the circumstances, and hopefully find some ways of learning from the earlier mistakes.
Many of us have had mistakes in the past, yet surely you are describing a level of mistake that many people would NOT want to experience, sometimes there can be ways in which each of us can try to learn from the mistakes of others - that may well lead cautions in terms of entering into certain loans and/or business relations, and/or cautions in terms of how we might deal with loans and/or business relations once we might already find ourselves in such a situation that we might consider to have potentials in going the wrong way on us.
