since i'm asking for btc, the loan would be repaid in btc, even if the price sky rockets or whatever.
I was thinking about going ahead, but then I read this. How would you pay back if price sky-rockets? I ask as someone who had a $20k debt when BTC was ~$10, and now have ~$500k in debt I probably won't be able to pay off before dying.

You should probably go for a USD-denom loan with a bank, CU, or even WU/similar transfer.
