I think it's a trust issue too.... They killed off a lot of customers with the suspension of the cloud mining and even before that, with the huge "maintenance cost" on mining, when it was still in operation.
I am one of them, and you know what they say.... "Once bitten....... "
The trading fees is a last ditch effort to keep the Titanic from sinking... it's a pity...They offer a GREAT service.
The maintenance costs are what has killed cloud mining plain and simple. I understand having to make a profit, but it seems the decision to suspend operations on that front was made rather quickly with no regard for their loyal customers. When this point is brought up, they tell you that you can switch on cloud mining
at your own peril in the user settings page. I thought this a rather mind-boggling addition unless they are hoping some greedy folks will actually try it and wind up paying more in fees than their GH/s produce.
