If I had some spare cash I would be buying around now, but since I don't I'm content to just hold on to what I have. I'm expecting this to be another bubble, so I'm just trying to work out when to sell so I can buy back in when the price inevitably drops. But yeah, long term expectation is that it'll increase with time so I've adopted a hold strategy as a rule of thumb.
I've thought about selling and buying back in, but at this point (with all the positive news surrounding BTC) I think it's pretty risky. There's just no telling when it's going to really shoot up.
