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and then sold it and made some good profits and I am now planning to buy some crypto once again and I admit that I am outdated on the crypto world right now.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! 
what token/coin do you want to buy at this moment...The market has been very bumpy in recent days, the value of many tokens/coins has averaged sideways. if you want to buy then just wait until next March because the possibility of the peak of the saturated market is that month.
