hmm...bitcoin fork will probably not happen. and if it really did happen, the outcome is: One, the first bitcoins value will skyrocket and other alt coins will follow. Second, first bitcoin value will hit rock bottom since investors will see no gain from investing further from a slow paced system and the second bitcoin's value will increase. Well this are just my thoughts, hope you pardon my ignorance.
The chances of the chain split weeks ago are low. But as of now it looks very likely to happen. We'll be having BTC and BCC(bitcoin cash)
