I’m a little surprised by the earnings listed here. My node with 11.7TB used space is making about $40 a month. It takes a while to get up to that level of income. Make sure you actually give it enough time to start using the space and exit the held amount time frame.
To get an indication of what you might earn you can use the more realistic earnings estimator I posted here:
If you want to know the held back percentage applied you can check the web dashboard or use the earnings calculator posted here, which will also show vetting process which could be relevant for payout amounts as well.
If it still doesn’t work out for you, that’s fine. But it would be sad if you give up on it before it even had the chance to be profitable.
