At present the market is very chaotic, many coin has nothing value but the price is high. This will change after about 2 years as the time in most altcoin's roadmap is after 2 years of product launch, then the Altcoin will actually return to real value. The Altcoin is really valuable at that price will go to moon. Do you think so?
that is true if it runs according to the white paper.
but there are many who became shitcoin. and currently there are many ico that are running the Q4 progress and this can increase market growth,
If the project has a strong team and an active community, then you should not worry about its future.
