I agree, that most of users better buy on the exchange its more safety.
It is not more safety, because crypto is very unstable. Moreover, any investments in crypto project is a venture investment - the investment with high risk, but also with high profits, if the project will be successful.
Generally speaking, the cryptocurrency field of activity is a huge risk, here we are discussing a project, and if it will be successful, investors will receive huge income.
They will recieve huge profits, if they will buy tokens right now, because they are selling with so high discount in comparison with main sale.
