TerraHash took almost no risk, they gambled with the communities money, not their own. How much have they actually risked of their own funds? Did they take a small business loan? Just to clarify, there is a huge difference between investors and customers.
Almost all of the current ASIC manufactures have absolutely no clue what the legal difference between a customer and an investor is, what they have done is tried to create a new category called investomers. If things end up going south for one of them they will quickly learn the law has no definition for an investomer.
