The market just works on the losses of some and the acquisitions of others.
It is obvious. The losses would have been anyway. But if people acted more optimally, the market would not be so unstable|volatile, there would not be a large number of scam projects. We can say that it would be easier to go through losses and wait for the development of startups.
I think that there are a lot of scams because cryptocurrency is anonymity. It is possible to conduct scam ICO collect money and do not have any punishment at all. Such unpunishment provocates people to create new scams.
