the analogy doesn't really hold to coinbase though. Shovels are a utility for mining gold. That would correlate to GPUs and other computer hardware. In that regard perhaps the VCs should be investing in AMD or Nvidia.
I imagine if you are a VC investing in this space, hedging between hardware, currencies, and exchanges/merchant services would probably be smart. If the market cap of BTC drops, does the market value of e.g. Intel or Coinbase drop proportionally?
Yeesh, now I'm getting worried that if everyone just puts all of their money into speculation instead of investment its going to be really bad for the economy in the long run...
That claim seems to require the ability to know the future. Bitcoin may eventually be superseded by a superior alt coin, and disappear into history.
