I think mining in legit cloud mining services can still be profitable, especially considering that those will not simply terminate your contract but offer to send you the hardware you've practically bought instead. So you can at least sell that hardware on ebay later on and have a shot at making a profit in total. An example of a 99.9% legit cloud mining service would be Hashnest, I'm currently looking into investing there. I'm not certain as to whether it is profitable or not, though. I am still looking for more first hand experience by users that have been invested there for a longer period of time.

It's a shame about all those lost contracts though. I imagine 90%+ of their customers were not aware this clause existed in their contracts prior to their hashrate suddenly disappearing. I feel bad for those people, they have been tricked by shady referral programs and terms like "lifelong contract".
