Best thing you can offer is transparency on hashing power real time.
When investors have a dashboard and can see and calculate alongside the operator then the mistrust levels are taken down substantially.
The other factor you need to be clear on is the fees. Cloud Mining is replete with fees being taken on every thing.
A flat fee for everything would go along way.
Transparency is something I definitely think would help in all aspects. My organization would have no issue being transparent about everything, as long as the terms/% profit ratios are disclosed and agreed upon from the beginning.
This is something I have been trying to figure out to offer to the clients, especially to some larger ones that I have other business relationships with. But no "plug and play" solution has been found yet.
