Yes, they are securities.  Offerings of securities in the United States require disclosure at both the state and local level.  There is a ton of case law from past scams mostly, where for example "shares" in profit from an orchard I think it was deemed securities.  Any investment where you get a return based on some allocation of profits from the seller of the note, hashlet, share, whatever, is a security.

The required regulations (which GAW is blatently ignoring) obligate GAW to provide financial risk disclosures, descriptions of its business, and all other "material" information about the investment and associated risks.  The U.S. has been pretty active in this area, and as GAW grows I am sure it will get the appropriate attention.
