I think those are Yam, Hakka. After ICO the price go down so much. I think Defi just a short trend.
Why do you say that DeFi is just a short trend? do you have a more complete explanation about this DeFi thing? because most people today already believe in the DeFi trend and will continue to do so for the next year.
I'm pretty sure that DeFi is not a short trend. It will continue, but only few best projects will remain. For example, Synthetix is one of the DeFi pioneers. They are working on the project since two years ago when the word DeFi wasn't around.
