How does staking crypto making money ?
When you stake a coin, your coins are doing some extra work by contributing to the Proof of Stake (POS) work that validates a block on the blockchain. Your staked coins are frozen for a period of time and used to validate transactions on a block. In exchange, you receive a percentage of the staked tokens as a reward.
Staking crypto is safe ?
Yes it is safe. You need to download the special coin wallet and enable staking there. Staking is nearly as profitable as the mining or trading of cryptocurrencies, and without risk. All you have to do is stake (buy & hold) some coins in order to get added to the mining pool
