99.9999% of cloud mining are scam/ponzi. Sorry
you are close to the truth (lol)
But my U2cloudmining system is not a ponzi sheme and not a scam.
It has worked with a U2 antminer...
It is working now without a moner
And if in the future a mine solution is found..;it will again work with a miner.
it looks fishy...(lol) but it works perfectly and all member will earn.
Winspiral, to be honest with you, i was testing your idea few months from the beginning of your project. Without investment, just with claiming every 12 hours as i good remember. I collect, i think, more then 40 shares. Then you make some strange changes, and my shares disappear. I don't know how, i just can not find them on your website. I'm not saying that you want to scam people, but you create this system so complicated and strange, that i just left it long time ago.
It is my personal opinion about your "mining"..
