Cloud mining is synonymous with "ponzi scheme" far too often these days.
And your rates beat out just about everything I've seen.

How can you prove you are not a ponzi scheme.
Obviously we can't know entirely for sure, but could you live stream your warehouse with the miners? Could you prove that you do in fact own that much hashrate?

You'll of course understand the concern.

So if you could figure out a way to prove that you do have the hardware, and the warehouse, (without a trip to Lithuania), that would likely help your cause a lot.

Also, the "no maintenance fees" bit scares me. How do you make money after the sale has finished? Are the electricity rates inflated to include the fee there?
