Staking is the process of actively participating in transaction validation in a proof-of-stake (PoS) mining algorithm and its variations. It was proposed as an alternative to the centralization of mining and reduce electricity costs for it. Over the past two years, Staking as a form of earning money on cryptocurrency began to gain popularity, as exchanges and wallets began to offer it. Staking will soon be a good alternative to ICO/IEO because a team can sell its tokens since the start of staking on an exchange.
