I need some advice, I had some crypto a few years ago and then sold it and made some good profits and I am now planning to buy some crypto once again and I admit that I am outdated on the crypto world right now. Can someone give a brief explanation of what DeFi is and what are your top 5 coins/tokens and where do you usually trade it. Thanks! 
deFI tokens have become one of the booming projects in recent times, but believe me now it's better to be in the top 10 coinmarketcaps such as ETH, LTC, BNB, POLKADOT, and NEO. it is too good for your assets than risking in deFI tokens that have no clear future
