Would You Advise People To Stake?
Why don't people just buy Cryptos that they can stake?
Yes, but beware of the risk. Storing your tokens or coins on a centralised exchange is not usually a wise decision because you can't tell if the CEX can have any issues at any time, which can result in you losing your coins. If the exchange gets hacked, it might affect your coins. If there is a hack on your account, your funds will be stolen.
When you invest in Altcoins that allow you to stake their coin, there's also a possibility that the project might not even make it to success, and it will just be a waste of time for your long staking period.
Everybody would not buy staking coins or might not want to stake their coin because they are just waiting for a slight pump on the token price so they can sell off and earn some profit. Another reason could be that they don't want to risk their lives.
