May i ask what kind of contracts you have purchased? And how long they are running now? I got 10MH 3mo Contracts and until now had no big problems except 24h inactive and unstable hashrate since 33 days (oldest one).
I have 100 Mh/s scrypt/3 months contract and my workers have been dead for 9 days now.
Support pushes canned response about developers working on the issue which is not helpful at all.
I'm getting the same response for any support request so it could be a bot maybe as the response hardly match my various requests..
In any case it's definitely a scam.
They took the money and are not delivering.
When I request a refund I'm being ignored or getting the same bot message.
So a word of warning to anybody considering contract purchase - STAY AWAY and keep your money!
