I've been trying to educate myself with all these forks etc but I'm getting confused why in November there will be a fork called Segwit2.

Regardless of what they are trying to do with increased block size and transactions, could it mean we will have 4 coins?

BTC
Bitcoin cash
BTC SegWit
BTC SegWit2x

So one main BTC coin and 3 Alt coin?

Its like creating money out of thin air.
