The market always has a lot of surprises and there are often new investment trends, so I think this is your chance to make money during this period. This year, DeFi can be seen as a topic mentioned by many investors and this trend will certainly bring a lot of profits to investors.
DeFi is having its bubble now. I can say some people are going to make money from this bubble, just like any other bubble that happened previously but whether it will be profitable for everyone, I dont think so.
Just because it is new and being hyped does not mean you should be get FOMO into it, you might very well be losing your money. With many scams centering around DeFi now after Libra and after ICO, one must be careful to put money into new DeFi tokens.
