I predict the price will go up as bitcoin scales, so it would go up if segwit is activated, but it would go up more if we got a successful hardfork blocksize increase.
If a fork is not decisive and we end up with 2 forks indefinitely, then both would probably be worth much less than half.

Assuming miners are rational they will switch to the highest valued coin in the case of a fork, so the fork should not be sustained for long.

Hey, i am developing this app, i made a bunch of other games on http://www.gameyey.com/mobile/all if anyone is interested.
Anyway, i already just published a new update! added some really awesome retro sound effects that i think greatly improves the feel of the game, in addition to some cool new design elements such as the combat-style health bar. It also has a new alien and slightly increased rewards, so enjoy! =)
