Seems like Cloudmining.website took the "Masters Cub" cloudy mining concept and ran with it:
We have launched the settings page. Now you can hold your payment and re-invest automatically. Both these features have been turned on for all existing customers as well as new customers. If you want to turn them off, you can do that immediately from the settings page. Re-investment will take place everyday starting from coming Monday.
Yep, its reinvesting 100% by default. Wonder why they did that
