Why the FUD Lauda?
Is this something you really believe?
This is not FUD. Consider a 50-50 split. Which one would you call Bitcoin? If you fail to comprehend the viewpoint, well that's not really my problem.
Now, remember that you had 5 regular bitcoins BEFORE the fork happened. After the fork, you have both 5 NewBitcoins AND 5 OldBitcoins. You don't have 10 Bitcoins. Bitcoins don't exist anymore, because the Bitcoin software has changed. Instead there are two competing altcoins (NewBitcoin and OldBitcoins), and everyone that had bitcoins before the fork has that same amount of coins on both systems.
You worry too much. Core supporters have been begging for large block proponents to stick with consensus. Surely, when that has changed those same people will stick with the new consensus. Anything else would be hypocrisy.
