Crypto projects are mostly DeFi by nature, but the term has recently become a hot trend in the market. Currently most of those projects are down at least 50% from the ATH price, so I think its trend is over, we will have to wait and see what the new trend of 2021 is.
In recent months, the Defi project has become one of the attractions for investors to invest their money and this positive trend has had a quite positive impact on the development of bitcoin prices and other altcoins in the market, at that time, the Defi project seemed to give a new breath to the rise of cryptocurrency slowly, but now it seems as if the Defi project is also starting to go down along with some fraud that occurs and of course it's pretty good and scammers are starting to eye some official token protocols for them to use as their means of fraud.
Yes, I think it's somewhat similar to the ICO of the past, helping to bring huge amounts of money into the crypto market. It can be considered a positive thing. After the hype it will need to correct and return to its true value.
