All theoretical profits of AMHash units sold at IPO are distributed as dividends. AM had better have received sales proceeds for the miners supporting the AMHash units sold at IPO.
As for the AMHash units that did not sell at IPO, there is no information as to the operational concept.
What you just said is completely wrong. AMHash is a 5 Ph/s mine created by AM using AM hardware. AMHash is simply a service of AM just like the Prisma is a product of AM. The profit from selling AMHash units are not distributed as dividends to AMHash holders at all. That profit goes to AM. What gets distributed as dividends to AMHash holders is the proceeds form mining, just like someone who bought a miner would get BTC from mining. As for the units that don't sell, they mine for AM, because it's an AM service.
AMHash is created by rockminer, not ASICMINER.
