Hello everyone I am new here, and I want to start investing, lately the
DeFi Project is good this year, there are many ubiquitous DeFi projects, both on Twitter and on the Telegram channel, Am I investing in every DeFi Project that can make a profit?

another one is DeFi becoming a promising business in the future?

On Twitter you said? Be careful with Twitter, there are some crypto coins on Twitter that are scam, do not be fooled, make sure you invest in a very popular DeFi project and since DeFi is gaining more momentum right now scammers will start taking steps too, be careful
It is true that on twitter there are many scams, but you can easily identify it. Just don't be greedy and don't trust others. I always use twitter to update the latest news related to this market, it is very effective
