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and then sold it and made some good profits and I am now planning to buy some crypto once again and I admit that I am outdated on the crypto world right now.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 futureMy understanding is that always find things that look legit and invest 90%+ of your money there, and keep a very small amount to make a profit with smaller ones, this has always been the case for me. So, invest into those top 10 coins, but pick like only 5 decent one of them, and also go look for a very small project. I actually own a coin that is not in the top 200 right now, it is very tiny and honestly I feel fine about it as well. It is just how I invest, with diversification and it worked out and made me a decent profit thanks to this method.
