I know you're exaggerating for effect but I'm having trouble threading the needle here. The "average VC tech company" gets nowhere near public market investors and, if indeed it is run "as a pump and dump scheme" would have a narrow impact on the LPs of the venture funds. Gotta imagine most LPs are sophisticated investors? Pension funds, that sort of thing.
Crypto, on the other hand, seems to be predicated on retail investors and consumers. So they do seem manifestly different as you have expressed them (maybe my issue is with the notion of the "average" VC-backed company?).
