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.
