Out of curiosity, do you guys just purely buy and hold, or take advantage of some of the spikes and sell off some shares to get free ones from the profits when the dips happen? Personally, I've been leery of doing that because I don't want to lose out when the price shoots up like I know it will, so I just buy and hold. But watching things, it does make me think that sometimes this might be a good option. I just personally don't trust my luck or timing.
