I don't know if everyone has noticed, but some people particularly like to promote hot coins. Every time a hot topic comes out, they write a bunch of concept coins related to that hot sector.
In fact, there’s nothing wrong with that; everyone is copying each other.
Moreover, because some coins tend to rise after a hot topic is released, not many can perfectly withdraw from it.
There’s an interesting point here: promoting hot coins may always be correct, even if the initial increase is only 1%. If you didn't profit, it's your problem.
