That's what I meant. But you are proposing to place profits from the real estate business into bitcoin, whereas I think it makes more sense the other way around

But you have to pay back the fiat you borrowed... That's just gambling on Bitcoin price within the loan term. In other words, leverage. Not inherently bad, but inherently more risky. You could end up stacking less sats in the end. What's the potential gain? 5% more than you borrowed? Not worth it for the risk and the headache if you ask me.
