Now promotion costs a lot of money because there are a lot of cryptocurrency projects and there is a big demand in professional promotion.
To attract attention to the coin promotion is necessary. A lot of coins appear every day. So it means that there is a big demand for the promotion.
That is why now the price for advertising and promotion is very high.
I agree that promotion is necessary, but projects must be useful for people to be in demand.
It is necessary to create and develop the platform that people will use in future a long time.
