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?
I can actually give you a clue about DeFi projects you need to stay the hell away from, be more careful around new DeFi projects because the hype will definitely attract scammers to this DeFi use case, DeFi projects have been around for a while, it's better to choose the old DeFi projectsanother one is DeFi becoming a promising business in the future?
