I have to tell you, I've been wondering that myself. I think it's very unpredictable. If there is a split, you'd end up with coins on both chains.

I can only tell you what I'm doing now - I'd like to buy more Steem, but I'm waiting at the moment in cash to determine a good time. Bitcoins pattern is to pull back after the kind of surges we have seen, and I'm hesitant to jump in now because money lost stings worse than money gained soothes.
