Well, you could go for the strategy that everyone does, which is buy low sell high, although it usually is very stressful and hard to predict. I wouldn't recommend doing this, since I have done that strategy before and I lost a lot of hours of sleep over it, but that may just be me. I would recommend buying some bitcoin now, in preparation for the hard fork happening on August the first, and then I would recommend holding it for a while, since after August first, there is a high chance that bitcoin will be taking a trip to the moon.
