Sure, we have good DeFi project, but there is still high risks. For example, yEarn Finance token YFI already worth 19 130$, higher than bitcoin. The coin was issued on July 18, 2020 and started with $35. A month later, on August 18, its price had already reached $12,800, overtaking bitcoin. Today, the token has reached a price peak in the area above $19,000. In a month and a half, YFI rose by 50,000%. A coin that is only a month old is already so incredibly expensive, I could certainly be wrong, but this is the last coin I would invest in, too loud to call it a bubble, but it can't be anything else. Such a young project simply physically can't create such a real value in such a short period of time, this price is conditioned by faith in further growth, not by project development.
It seems that, indeed, the YFI token grew in price mainly on the belief of investors in its further price growth. For a while, this token stopped growing, investors' faith was shaken and its price began to fall. Today YFI can be seen at position 24 in the CoinMarketCap table, although a few days ago this token was ranked 20. Its price dropped to $ 31,871, and a few days ago it was above $ 40,000. In one day, YFI's capitalization dropped by $ 45 billion. If investors get scared and begin to take profits by selling YFI, then in a few days, or even hours, it may fall below the bitcoin price.
