times have changed and what you are doing is admirable. do not tire.
I agree its likely even early investors in these will no longer break even, and that may have some impact. Compare it to all these 'bitcoin arbitrage investment' ponzi's that no longer seem to be making headways these day. Then again I thought the same after Pirate, and mining ponzi's are far superior in concept, its really Ponzi 2.0: no bankruns, apparent short term profit yet plausibly long term investor loss. Its perfect. So I think it will be a while before that stops.
the harsh realities of real, honest cloud mining can be clearly seen in the difficulty charts and even a small bit of research can show massive realities to the investor regarding costs and contract longevity.
eg. I'm still mining my own rigs, but they are (most likely) far from exceptionally profitable at the moment - even though i'm mining at 0.53w/GH, I do it at home as a hobby and I take my losses on the chin for the simple fact that I believe in bitcoin in the long term and all the paper wallets that I stash away, will do good for someone in my family, somewhere down the line...
A cloud company has far more necessity to service overheads than I do and as a result will always be forced to add realistic fees, which, in the end relate closely to the costs which I endure as a hobbyist at home.
One serious problem with these ponzi schemes is that they are detracting from the real businesses. there are some very good companies out there who have decentralisation and the commitment to providing mining for little guys like me , at heart and the more naive 'investors' who plump to send their BTC to a ponzi scheme like terabox, because it is cheaper, the less we are able to decentralise the network. I'm not saying this as an investor in anything, but just one who is concerned for the future of bitcoin as a whole. If we do not act, and continue to act, the real, honourable companies who are vying to sign up these investors will end up being sold out to massive conglomerations who care not a toss about who holds what portion of the network.
in the long run, it's a very serious situation and I, for one, will not be swayed from seeing the bigger picture and continuing to point out the realities.
