I don't see any difference between the both of them as long as they are still asking for collateral's. Well, I know that cryptocurrency loaners can never give you any loans without collateral and that is right because some. People are going to run away with the money, which is very bad, so they have to give something in return in case they decide to act any way stupid then the cryptocurrencies they have given as collateral would be used as a way to recover the money they have taken from the lenders.
