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.
If we plan to hold long-term then staking on single coins is very profitable, so don't staking by buying pairs of coins or tokens, for example I am staking CAKE with the autostaking system, so the coins generated are also CAKE and we are only staking CAKE so it is very profitable if we hold on for the long term.
To be honest, I'm not interested in staking because I'm more comfortable with activities outside of staking, namely holding coins while waiting for the price of the coins I hold to increase, after that I buy again at a lower price.
