Staking in crypto is basically like putting your tokens to work by locking them up to help secure a blockchain network. In return, you earn rewards kind of like profit on a savings account. It’s common in coins that use proof-of-stake (PoS) instead of mining. The longer you stake and the more you put in, the more you can earn. It’s a way to passively grow your crypto holdings, but you should be aware of risks like price drops or lock-up periods before you can sell.
