Call me crazy, but I think it makes more sense for me to make minimum payments on this 10 year loan I have for new HVAC unit at 10% interest, and buy more BTC every month instead of paying additional principal to payoff sooner

The CAGR on BTC outstrips the additional interest I would pay on fixed payments with weakening dollar.

So long as I can service the debt, it makes more sense to buy BTC with the extra cash. What am I missing?
