No traders at the exchange - no liquidity - it is bad. Many traders at the exchange - a lot of liquidity but a lot of speculation too. It is bad again. What is good? When there are a lot of liquidity but no speculation. How to do this?
I do not understand why games in the market are harmful to the project? As a rule, it is important for short-term traders. For investors, it is important that there is liquidity, and they can buy/sell without a significant change in price.
If there is only a slight change in price, then such a coin can bring a small percentage of profit. Not all traders will then work with it.
