Depends on your debt load. Going to guess it’s>25k since there’s the option of putting it all there. I’m saying put 1/2 into the highest percentage rate debt and 1/2 into B. If you have zero or little cash savings, do thirds. Having available cash makes life so much easier. Unless you have that tendency to spend it all.

I believe that the best option is all in bitcoin, but covering debt for 75-100% makes you feel relieved of future obligations, but you may lost an opportunity to buy cheap bitcoin
so if you have quite stable income then:
pay 5-15% of the check to cover debt
look at this like you took a credit to buy Bitcoin
