10-20% correction is nothing when you compare it with 1000x what almost all of these tokens did in the past few months. Is Bitcoin dead when it comes back to 10k USD level? Probably not because it has grown from 0.01USD. 
i think its too over reactive if 20% correction mentioned as died. its not only defi project that have negative gain in crypto market, almost all coin even top 10 do the same thing too. i am agree with your opinion , we should not worry and if look price histroy we still see extreme growth in most of cryptocurrency.
