i'm sure that defi is not like trending tool but mostly a great decentralized concept and it even will replace traditional centralized exchanges. i prefer to choose credible defi and especially - dex projects to invest
We cant deny that decentralization is always the best but in the reality we've been facing, we do much prefer on using up CEX which is clearly evident.
Rise of DeFi? I dont see anything special, there might be some projects which did succeed but most of them are just like into those ICO projects that had flooded out the market.
Its not a threat because this is just an another project that do focuses out on a certain key area.
