Because of FATCA and friends, essentially all financial institutions in the world now report to the US and follow its rules. If you are not a US taxpayer, and outside the US, they don't directly apply to you, but they have already affected the regulations that do apply to you.

You should be aware that the decision of jurisdiction can pull you into courts you never knew existed, in jurisdictions you wouldn't imagine could exist. Finding a country that won't extradite you may become an issue of treaty, or even a string of treaties. IANAL, but I sat in on one of my brother's international law classes, which quickly convinced me to not fuck around in that arena. Lawyer up early.

Most countries have securities laws, not just the US.

Are you sure your country doesn't?

> 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.
