If it someone I know trustworthy I may be able to lend him/her some money in crypto if the borrower is familiar in crypto currency and its characteristics. In addition, it would be tough to let the borrower let his/her decision in an amount of money to be converted in crypto as the payment because crypto price tend to change overtime. It is just a matter of me losing much more a lot based from the conditions or I may be gaining more than the money I let the borrower borrowed.
