ADA Lite — Staking, Delegation
Few things to note first:
There is no danger of loosing your funds, as your funds will never leave hardware wallet. You are just telling the network that you are delegating your stake to the selected pool and not sanding that pool any of your ADA.
There are some parameters to consider:
Cost per epoch: This is a fixed amount of ADA that the pool operator will get and will be substracted from all the rewards the pool creates.
Profit margin: Is a variable reward for the pool, percentage of reward sum that will go to the pool operator.
To play around with this parameters you can check the official rewards calculator
If you want to consider us; our pool is www.ada247.net TICKER AD247. APP fee is just 2%.
Note: Currently you can only delegate to one pool per wallet.
Next type in or copy/paste the ID of the pool under Delegate stake. You should see the correct staking pool information. Click “Delegate”.
