Yes.
> Why?
Because VCs don't actually need their portfolio companies to be successful to create ROI. A16z can essentially pump/dump these companies more easily because they have tokens associated with them.
A good example is Dfinity. It claimed to be some revolutionary way to decentralize web hosting. The claims were vague, and when I looked into it on behalf of a friend, I found that it wasn't technically accomplishing any of the things it claimed.
They pumped tons of money into a big token launch, which functioned as an exit for a16z and the founder of Dfinity.
