Segwit2x is the biggest problem, since it's a direct attempt to takeover Bitcoin, other forks are a smoke screen to scare people from potential forks (all this FUD that Bitcoin will crash if there will be split), while presenting Segwit2x as true Bitcoin. The real fight will be when miners with their 85% hashing power will fork into 2mb blocks in November, I hope people won't get themselves fooled.
