Paying out, does not make it legit, proof of legitimacy does. They haven't shown any proof as of yet but claim they will do so in a couple of weeks. Gives them a fair bit of time to collect some BTC and run. They're just as legit as every other "cloud mining" service that ran away with the money after failing/refusing to provide any proof of legitimacy.
Also, none of these new "cloud mining" ponzis can get enough initial customers and collapse within days.
