I'm still considering whether to hodl in a cold wallet or to convert to a few altcoins... Also I think there will actually be a lot of opportunities during the uncertainty phase after Aug 1st - in lending and shorting on an exchange - if you're willing to accept the risk.

The price may fluctuate a lot during this period but in the long run I think there will be a correlation between the cost to mine a coin and the actual value of the coin.
