I knew crypto detractors were going to have a field day with this one. ;)
With DeFi, you're simply exchanging one type of risk for another. Without due diligence you're pissing your money away- as it is to be expected. And as it was brought up before, this was an unaudited contract that had been running for what, weeks? Months?
Personally, I cannot say I understand DeFi deeply enough to get into the intricacies of "yield farming" and such, so I just avoid it altogether. Only have a relatively small amount of USDC and DAI accruing interest on Compound, which has at the very least been audited [0] a few times before, but even if it were to go tits up tomorrow for whatever reason, at least I understood there was that risk.
