There is little doubt that many ICO's are 'scams', and some people will get hurt financially because of it.
The challenge with regulations is, it's easy to quantify the harm they try to stop, but it's harder understand the impact they have on limiting future creation / innovation etc.
Tokens / ICO's have created a whole new, far more accessible way to fund and invest in new technology. Making it far more equal, fast, open and liquid than the traditional process.
Regulation is coming, as it should. I just hope it's done with an eye for encouraging the right type action, rather than just trying to stop the wrong.
