If the ICO is under SEC review, will it be safer than most ICO out there?
Not necessarily. It's more so that this ICO will then comply with all legal terms, but that doesn't mean anything when it comes to you as investor. If Overstock messes up in one way or another, you are still left with heavy losses. SEC is nothing more than a hoax watchdog in reality. They rejected the previous Bitcoin ETF's because they can't 'guarantee' that investors will be safe, while they have done nothing to protect investors when it comes to all the failed (non crypto) ETF's having resulted in millions and millions in losses globally. The SEC only wants to make sure you aren't doing anything that goes against their own values, where if they think it doesn't harm themselves, they from that point don't care about what happens after that. They are a bunch of hypocrites at most.
