Thanks for all the replies. Seems like I am out of the loop in crypto world. When I started the thread, I did not have CEX or DEX in mind.

Seems like I need to get education. So asking 2 things:

1. Is there any place where I can get up to date & learn about staking, CEX or DEX properly. (site or youtube channel like babypips)

2. Is there any way I can earn (like Binance earn) & keep my coins to myself?

Thank you.
