I think we are starting to see the first wave of institutional involvement in this space. 

Pension funds, college endowments and other asset managers control trillions of dollars of capital so once the flood gates open its going to cause prices to surge.

I would expect to see a large increase in institutional investment over the next 6-12 months. 

As with any investment, you want to be invested before the whales jump in and cause prices to surge.
