If JihanCoin garners the majority approval of Chinese Bitcoiners, yes, I will use JihanCoin, and I imagine it will work out splendidly. This Chinese FUD is unwarranted and biased. I imagine if the majority hashpower were in the USA, noone would be fearing centralization.
However, it will not work better for Jihan himself or for Bitcoin as a whole, so I pretty much wish that Bitcoin doesn't lose Jihan's Hashpower.
Since I do not like the fundamental principal behind UASF coercive deployment, leaving Jihan little choice in my view, I would also have a hard time supporting the alternative chain on philosophical grounds.
So yes. I will use Jihancoin.
I do not expect that we will come to that though.
