I agree. You can see a bubble from a mile away. Just look at all the crappy projects and their market valuation. And the people that hype them.
I can spot the difference half a year ago and now. Back then people really took their time to analyse everything about the project, not they just go with the hype, supporting projects with where their github has last commit 3 months ago and totalling 3 commits, market valuation 100 millions.
But I think like in every bubble top projects with real world value will survive.
