Yesterday, I made my first withdrawal of 10,000 sats from GoMining. It's not that big I know. But I can confirm that this Cloud Mining service is legit. Will work hard on upgrading my miner, so that next time it will be a much bigger payout.
You might want to consider to only withdraw when you have a larger amount as 10k is quite small for a utxo. When fee goes up it could wipe this utxo out.
