Staking gives profits to investors just like mining or trading of cryptocurrencies would.  It is comparatively less risky than trading.  Those who want to stake should buy a particular token like ETH or others. Then you have to invest the token in a staking pool.  The actual profits that you can make from staking will depend upon how much you invest in the pool and for how long you choose to invest.

You can stake your coin for a particular period of time just like you would in a fixed deposit.  Thus, you do not need to hold your investments forever like Warren Buffet. There are different types of staking period with different types of reward.

Staking in cryptocurrency is an excellent way to make passive income.  For example, if you stake ETH, you will receive a certain percentage of revenue in return; similarly, there will be different returns for different token types. If you have different crypto, you can shift staking different types of crypto.

In Tezos, users are allowed to stake and earn passive income via delegation. By making use of a staking reward calculator, users will be able to estimate their monthly earnings.

DeFi Staking is the hottest trend in the cryptocurrency industry.  Defi staking might be difficult to understand for those who are new.  It is very much similar to traditional staking, as opposed to returns from savings and traditional accounts.  When you invest your value in crypto and lend it through Defi, you will be able to earn higher rates of interest. Since, there are just a few intermediaries, the profit-making potential is more.

Just like you will lend your fiat and earn interest in a fixed deposit, you convert your fiat to crypto and stake the crypto in a lending pool and earn interest for it. There are some people who earn as high as 23% plus APY (annual percentage yield) for staking the Binance Coin.

There are also those who stake their value in Algorand (ALGO), Kava (KAVA), Texas (XTZ), Cosmos (ATOM), and even Tron (TRX) to earn up to 12% APY directly into their TrustWallet.

By staking your value in the blockchain, you become one of the validators in the system. Every kind of PoS Protocol depends on users staking to sustain the network. Everyone who stakes is a validator—the more number of validators, the more powerful the network.

For Ethereum 2.0, the minimum requirement for staking is 32 ETH.  Different blockchains have different staking requirements. There are other pooling mechanisms that allow staking even less.
