I hear the most dreaded criminals tend to breath air and a shocking percentage of them are found to be mammals.
Jokes aside, How do you compare an ICO to cash? Its more closer to an IPO process.. if you started allowing listings in the stock market backed solely by 5-6 nice LinkedIn profiles and some 'white-paper' I'm sure the exact same people will list their companies in the stock exchanges as well.. Unlike an IPO, there is no vetting process, there are no mandatory disclosures or oversight.
That is freedom from central control, sure. But, the cost of freedom is the risk that gets loaded on the part of the investors. This gap is wide open for people that are thus inclined to cheat and make a quick buck. I am not berating crypto, but, I have a lot of confidence in criminals going after easy money that doesn't have too many down sides.
