Which ICO was not a scam ?
Scam =/= terrible investment idea. Tezos and Filecoin, for example, are not scams. They are serious projects that are attempting to bring something useful to the market. That said, they raised wayyy too much money, and may end up being terrible investments that don't return any profit, but that applies to many startups as well. PlexCoin offered guaranteed 1300% returns or your money back. That is a pure scam.
I see ICO's as marketing investment opportunities to unaccredited investors. I thought unacreddited investors in the U.S. are legally allowed to invest in public stock, and approved securities (like bonds, precious metals, etc) and only a handful of other things.
The notion of accredited investors legal requirement to invest in tech startups is that tech startups are inherently very risky, and the average person shouldn't be allowed to put their life savings behind something so risky. By this logic, it strikes me as very odd that ICO's are legal for U.S. citizens to invest in, and my guess is it's because the SEC hasn't come around to regulating them yet.
Does that sound correct, or is there reason to believe the SEC (in the long-term) will be okay with unaccredited investors investing in ICO's of tech companies? Are there other things with a similar risk profile that unaccredited investors can invest in?
