Almost DeFi, "YFI" family and .finance domain bounty threads now seem like all scam. They just try to imitate the Defi trend, using hunters to promote their project to sell tokens on uniswap before turning to exit scam.
They are copy-cats of copy-cats. Not gonna trust those defi related projects without any solid foundation. You will know their capability even browsing their website or whitepaper, if there's any. Users should not be enticed by these DeFi projects as they are just trying to get some money from naive buyers (in uniswap in particular). Expect to see more defi projects turning to huge blunder.
