Why do you think so? During ICO, you can buy coins with a good bonus, especially on early stages.
As mentioned above, the prices on the exchange are falling so much that no bonuses compensate for this. Unfortunately, this happens in most cases for more than six months.
It's true. I bought one project tokens along with bonuses. But still, I lost 10% of the deposit on the depreciation rate. Now I am waiting for the growth rate of the coin.
