suspending cloud mining doesn't necesserily mean that they stop mining internally, does it ?
That's why it will drop 10% instead of 30%+
unlikely it will drop like that. The cloudmining contracts might end, but the hardware will still exist. It may likely just be used for CEX's private mining.
I expect a 0% diff change because a lot of 1w+/gh gear will shut off but be replaced by newer S5/SP20 gear
