There are few projects offering crypto loans like
SALT or
ETHLend (they only offer crypto loans atm), but I have not used them yet. I'm more bullish on
NEXO, which I invested in recently, cause they are planning to issue credit cards in a month or so. You can get instant crypto-backed (only bitcoin for start, soon NEXO token) loan on their platform and can spend it using plastic in any shop, so it's a perfect solution. In addition NEXO token is a security and you get dividends just by holding it.
