Interested in the answer. If it's credit, that has to be paid back in fiat and if you're in a Bitcoin Standard (you don't have fiat) that means selling and a taxable event unless you're paying back with every paycheck which is a huge dip to any daily liquidity you might have to buy stuff like normal and not feasible. If you have a bunch of cash laying around to pay the loan back we'll... Then maybe it makes sense. For now bitcoin backed loans still barely compete with a personal loan if you have good credit. If you don't have good credit well... And I assume Bitcoin will be the presine collateral and in the future fetch a much lower rate.
