To speculate a bit, the reason for why the really big investors apparently avoid bitcoin is because:
1. It's too late to get into the bitcoin game. Too many bitcoins in circulation today. Why make the early bitcoin investors trillionaires so that they can dethrone you as a leading financial investor?
2. Can you imagine a big bankster messing with bitcoin paper wallets? I don't think so.
3. Do you think the big professional financial trading systems can be used for investing in bitcoins today?
4. Do you believe the big professional financial traders want to mess with something unregulated?
