Of course yes, staking coins is profitable because one typically earns interest just for holding coins in a wallet.It doesn't necessarily require more investment to generate a profit, one could call it profitable. Staking is as profitable as the mining or trading of cryptos, and it comes without risk. It is a good idea 👍
Staking isn't to make big money, it's just to increase your profits. Nevertheless, it is an easy way to earn a few profits. Taking profits will not be possible if the market starts to go down. If the exchange or platform you're staking on fails, you could lose it. To begin with, you should seek out some real projects in DeFi that have good yields on staking.
