Yes, in terms of opportunity for now in seeking profit it is great to always follow DeFi, but everyone will not know how long the DeFi system will last because DeFi is a new system that has just been developed at this time.
not a newly developed one, but I think it just became popular in the crypto market. Unfortunately, even though it's new with a lot of enthusiasts, there are already some that look scam and are indicated as a scam. it will worsen the crypto market if many investors are deceived.
