The trend will not last forever.
The hype was part of the problems, but that doesn't mean it can't be very useful to people in the future.
I actually prefer having a project properly built to serve its purposes before you get people to start investing their hard earned money into it. And if it doesn't have much useful uses that are worth selling to people I care about, I wouldn't bother promoting it. If I can promote it to people I care about, I can promote it to anyone.
Hope they understand how to put it into good use. When you think less about yourself and more about how to benefit others with good things, understanding will come.
