Is this ICO open to US investors, given it's a "utility" token rather than a "security"?
Probably not, since basically every ICO out there prohibits US investors from participating, utility or security ones.
Yes very well, in the United States is not allowed to follow the ICO or more precisely prohibited, in fact America will actually make the project ico stronger in terms of funding.
Actually, ICOs are prohibited to US investors, so every ICO can't target the US' citizens, but that won't stop people from participating using VPN, US does not forbid for having an ethereum account or using it, and that is just enough for people to participate, simply put, ICOs can't advertise they are letting US citizens participate, they must make an announcement with specificating US citizens are not allow, but they can't know if one or more are actually doing it anyway, because blockchain makes them anonymous.
Exactly, ICOs are decentralized so they can't be blocked by government. Use VPN and you can still invest
In fact, regional political regulations can not prohibit ICO and encryption secondary market
The encryption market is a global market, and different regions have different regulatory policies in the encryption market.
Small areas can not form regional policies that affect regions around the world
People can attend VPN, too many ways.
The trend of globalization is not a few people want to stop cessation
It is impossible to happen
