So if someone is a BTC holder and buys 10.000 LTC, intentionally, one block prior to the fork, and sells these 10.000 LTC back one block after the fork, then he'll suddenly have both his BTCs and the LTCs on the alternate fork.
Now, if and whenever some exchange adopts xLTC, then he'll have 10.000 LTC to spend / dump in the alternate fork. Yeah, I mean, what can possibly go wrong there... hmmm...

I don't know much about hardforking and coding but this is bull.
There have been mandatory updates before that can kick you of the hardfork unless you upgrade.
It shouldn't be too hard.
I predict GPU miners will do the same as they did 12 months ago:
they left BTC when ASICs took over the network.
Now ASICs are taking over the LTC network and
GPU LTC miners need a new coin to mine.
Hirocoin will be the next coin to watch. It doesn't sound as "black and illegal" as Darkcoin, so there will be no problems for shops to accept it.
I predicted the same for LTC 12 months ago and people told me I was crazy. Well... Who's crazy now?
