If you do the following:

1) Make a product
2) Sell it for a price that will allow people to profit after 30 days (don't do what Avalon and AsicMiner did, which is capitalize of the fear of not owning one)
3) deliver it too some bloggers
4) open you manufacturing facility to be viewable (photos, webcams, etc)
5) have a supply line that can ship a product to a user in < 30 days
6) be ready for a flood orders

then you sir will have a crazy cash machine on your hands. . ..in the end with bitmining, it's the hardware makers that will make "bank"
