I'd honestly be curious to why this comment is being downvoted so much, as I've often found myself agreeing with this refrain.
To pre-answer the common rebuttal I get, that VCs are taking moonshots at the chance of a VERY HIGH return; I'd ask why not look at VC investments in the sense of a more traditional portfolio, where you'd have your growth stocks, your value stocks, etc. If I could find a vehicle that reliably gave 20% YOY I'd throw fistfulls of money at it.
So can someone enlighten me as to why this isn't a viable way of looking at VC investment?
