Everyone saying about having 0 on their wallet and checking it out on the block chain.. Doesn't really understand how their system works...

They will not literally deposit any money on the wallet they generate to you as it would have unnecessary network cost for them.. What they do is just add an entry on their database pointing that address X has Y balance... And when you ask for payout.. Then their internal address will send out the money and deduct from the database...

Só tracking your NH address on the blockchain won't work.. You might be able to see it through if you have made any deposit to it previously.. But you might never see that address sending funds directly to you.. Or you might even see that it has been zero out long time ago....
