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and then sold it and made some good profits and I am now planning to buy some crypto once again and I admit that I am outdated on the crypto world right now.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! 
Here's my top 5 coins/tokens that I trade the most:BTC , ETH , XRP , LTC , BCH Why I chose them? simple, Volatility + Liquidity. Where do I trade them? Links are indicated on every coin/token that I've mentioned. You're welcome.
You've got an awesome platform for these coins, I'm using kucoin as well and the volume has been really great there so far. I don't like complexity when it comes to trading so I usually choose the platforms where I feel comfortable trading and where I can navigate through simply.
I have tried a lot of exchanges before but only few of the stands out, even on coins that I trade I tend to be really picky on where to put my money.
