But I want to know how it works and what kind of risks I should be aware of. I need help from experienced people.
Should I continue to participate in mining or change to other better projects?
Coins that use Proof-Of-Work consensus (BTC,ETH) need miners who confirm transactions and add them into blockchains. But consensus that is more popular today is Proof-Of-Stake. It requires validators that stake their coins and get APYs for that. I know that coinbase is a platform with a good reputation, so you I think you can continue staking there. But again, don't forget about risk management and don't deposit everything in one pool on one platform.
