No one force people to send assets in ICO. This is their free will. Banning ICO is taking this freedom from everyone. But I agree that there is no good way to save participant from scamming. Information is the key, but there is a lack of it, and so you have to think of an ICO as a crowdfunding rather than investment.
I just wish you only good choices ;)

I agreed it too.. there are good and "bad" ICOs floating ard.. is all about how good the marketing is to prove that their ICOs are worth to invest in.

The basis of a free market is such we don't stop it and let competition weed out the weak.
