You should put your allegiances aside and put your greedhead hat on.
BCH, or whatever it is, is going to have a smaller supply than BTC no matter what. Plenty of people will be too stupid or lazy to claim it. Others will have sold straight into the hands of pumpers already and will do so again when Poloniex and Coinbase release them.
If it's a pure alt, and it is, then it's inevitably going to become a whale toy like all the others. On top of that it comes with the big block agenda baked in and at least a few of them have very deep pockets and the hunger to scare BTC.
A super pump is inevitable in my opinion. Selling at this price level is fine for something that cost nothing, but it was created to make a point so sell it when that point is being made.
It'll whipsaw around forever now. The ETH flippening scared enough people, can you imagine how much a whale inspired BCH flippening would make?
And if there's another generalised alt tsunami upwards never forget the classic noob mind set of 'hey, it's Bitcoin but it's CHEAPER. Wow.'
