We always see the price rise for a short period after the listing in the exchanges or after IEO, but soon price be come down,
this may due to two reasons:
The first reason is that the coin or token has no real value.
The second reason is the large sale of those who got his coin free such as airdrop.
Isn't that true?
Do not forget about such a simple reason as pumping a coin, this is a feature of the cryptocurrency market, it uses exchange mechanisms and trading bots.
In any case, there are such projects that try to control the price of their coins and they succeed. Although I dont know where this path of manual regulation of the market price will lead, since this applies primarily to new cryptocurrency exchanges. As an example, I can cite the BCNEX project, where for quite a long time their coin has been at the price level of $ 0.12.
