I strongly believe that while they might not have invested directly in Bitcoin themselves, they might have been doing so through proxies for quite some time now. It's of course not entirely the same, but the main point of importance is that the current difference might cause these entities to go full nuts on Bitcoin instead of conservatively letting a tiny bit of their liquidity flow into this market. I however hope that at some point we don't have to look forward to large investors entering the market anymore, because the only reason people like to see this happen is because of the price that will go up. It has nothing directly to do with Bitcoin as always....
