It depends upon what type of investment you are looking for short term investment or long term investment.If there is hype about the coin the it would be better for short term but if its technology is not that unique or good then it would suffer in long term investment. I generally would see use or utility of the coin but even if the coin has great utility but has no hype then it wouldn't survive.
We're talking about "which one is important"? We are not pointing out where we can make more profit as it wasn't just all about investment but to say which one is more beneficial to the community. If that we think, then we choose those projects that have utility as important.
We can figure out how these shitcoins make hypes, they usually just die shortly. If we are into that projects, how we could gain trust from the community? How we could make use of them if they have just gone after a month/s or week in the market?
The thing in here is to see crypto projects become sustainable long-term, not justshort-term.
