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and then sold it and made some good profits and I am now planning to buy some crypto once again and I admit that I am outdated on the crypto world right now.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! 
I don't think if this is a piece of good advice but I want you to listen to what is in your heart and ask yourself also if you are already prepared to lose or not. Because in the first place, you can never tell about the RIGHT?PERFECT TIME for investment. The reality is that investing in crypto at a cheaper price will be a good time but still, it wasn't be called the right time, this only gives us a higher chance to make a profit unlike in the situation when you buy at peak season.
