> Filecoin's ICO seems to be one of the few exceptions to follow securities law.
The SEC commissioner said that no ICO has registered as a security so far. Given that Filecoin was one of the only ICOs to openly advertise themselves as being a security, it seems like they could be in even more legal trouble than everyone else.
They filed a Reg D exemption, which is different from a registration, but allows you to legally offer securities if you comply with a narrow set of restrictions.
