Maybe in some point you are right but not all inside US are aiming for long term support some of them are also have the same point of views regarding to quick benefits. Maybe the ratio is more from China who wanted for instant profits when the project got listed and completely sold everything to take the profits that they are after. The concept still depends from investors mindsets there's no certain venue or people to be exact.
I can tell you that most investors of altcoins in particular only want cryptocurrency project now for a short-term profit because they have already given up on the long-term profit of it since the ones they have had in the past has not really yielded them much profit.
Chinese people don’t believe much in cryptocurrency, although they will actually engage in it to get the benefit of it, and that is why they are more likely to always pull out on every project once they get a little profit, but it is only bitcoin that I know is the project that most people of the world wants to hold for a long term, because they believe in the future and the long-term benefit of it. So, I would not expect any Chinese project to really stay long in the market as it will be a project for pump and dump.
