The Bitcoin community has debated a potential hardfork for over a year now. There have been various solutions proposed to change the cap on block size and increase the amount of transactions that can go into any single block.
Leaving aside the discussion as to which approach would be the best for Bitcoin in the long run, we can agree that there is a disagreement on the issue and any hard fork that may happen will not be as unanimous as the previous forks were. Looking at some recent examples, we can expect that any contentious Bitcoin fork will create a split in the network.
