my question is what is difference between HODL and staking
hold is expecting a profit by holding a coin until the price of the coin increases. Staking is an attempt to make a profit by betting. the process of holding coins because risking is very large the risk that will be obtained. and vice versa, if you are lucky, you can get more than 10x the profit. that's pretty much the difference.
It's better to wait until the price increases and we can freely make the decision to sell it or continue to hold it than having to take other risks because staking has rules that must be obeyed if you want to join, for example sending coins to other platforms with a predetermined time period. if you meet the requirements then the participant will have a steady income meaning the coins will increase
