never) borrow money in a cryptocurrency that means signing a sentence for yourself .. just imagine, today you borrowed one ETH, which cost $ 100, and woke up the next day and it turned out that you already owed $ 3000 as the rate went up) I do not argue, maybe on the contrary, but there is also a "law of meanness" that will definitely play against you) so it is very dangerous to occupy a cryptocurrency
I agree with you. Borrowing funds in the form of cryptocurrency should be at a fixed rate at the time of the transaction, otherwise you are at great risk of giving back much more than you borrow.
