Borrow something that is very volatile? That's crazy. For example, you borrowed 1 BTC and then you get $3,000 for cashing it out. Now, you have to spend $5100 to buy BTC and return it. And we are not yet talking about the interest.
You are correct regarding the volatility of cryptocurrency but the OP is stated that what if there is a coin or token that has a low volatility or maybe a stable coin like Tether, would you borrow or not?
