Instead of just holding coins for an uncertain time, it is better to staking to increase profits. Each coin has a different staking result, I can't say how much I get every month because the staking time is different for each coin.
You can actually know how much is the possible return by reading all the terms and conditions since before you stake, information will appear especially the APY percentage. I don't stake that much since I have limited capital and I can't do this because small money means small profit on staking so I choose to actively trade it to be more profitable. Profit on staking will already vary on percentage and the value of the coins/tokens you're staking with, I suggest to compute first before you let your money stake for a small portion of profit.
