YFI is really crazy increasing its price so so high only in several months. Is this only a hype or others? Moreover, more surprisingly, it passes the price of BTC only in some months. In this situation, many people may have got very high profits for sure. However, we do not really know whether the price will always increase or it only hits the hype and then down to earth again.
So based on this condition, personally, I have no YFI and still prefer to hold BTC.
