Im looking at their website and cant really get my head around how it works.
If you us a normal address is there a minimum you can get? Now I have requested the payout of 3500 is that the end? Is that 3500 gone?
"Payments are sent via Microwallet.org. Your withdrawn funds if lower than 5800 Satoshi are stored there and released to your BTC address when equal to or greater than 5800 Satoshi to minimize fees!"
It seems 'you' don't need a microwallet account but 'they' use that service to store your balance until it gets above 5800 Sat, at which point it will then be sent to your wallet.
You don't want to withdraw anything less than ~ 5500 Sat to your wallet because that would be dust. The transaction would likely never confirm and if it did make it to your wallet you would have a hard time spending it.
Please let us know how things work out for you once you get above 5800 total.
Btw, microwallet has proven to be reliable and is the best way to get aggregated payouts from most of these faucets.
