"Still, all investors should probably sell their coins within the first six months, the study found."
This is a baffling statement, mostly because if you sell your "coins" to someone and they keep them too long, they will lose everything. Which could lead to liability questions.
I mean, you buy those coins and sell them as fast as you can, because you know that they won't be worth anything within in days or weeks, it could be argued that you committed security fraud. Well it could also argued that the ICO itself is already fraud, because of the huge risk involved.
