I'm struggling with this claim. The thing is, he did not sell the miners. Rather he sold shares of the miners. He also made it clear that he is not responsible of Hash Fast does not deliver.

The important point here is that he was just offering to run the equipment for you and others. It was you who took the risk on Hash Fast delivering.

Your Mac logo example isn't right. Sure, if you have no computer, you can't make logos. However, if you bought a different computer you could make the logos.  With the equipment used for hashing, he is not buying the boxes and leaving you to dry. Rather, he is collecting money from people and using that money to buy the miners. Sometimes, he puts a little of his own money in to buy miners, too, which is why I think he marks them paid.  He indicated somewhere that when he gets to about 90% funded, he buys the miners.

You really shouldn't complain to waldohoover. I'm sure he is as unhappy with Hash Fast as you are. He cannot control what the company does.
