I'd argue that using lending services is inherently riskier than leaving your funds on an exchange. An exchange can keep 95%+ of its funds in cold storage and thus limit the risk of loss. A lender has to keep funds moving out of their control into the hands of third parties upon whom they must actively manage risk of default.

Manage your risks.

Do your due diligence.

Don't complain if you risk it all and get rekt.
