At the risk of fuelling anyone's paranoia, there is a Chinese pool that will prioritise transactions relating to their business, but there's still absolutely no evidence that US transactions are being, or even can be, rejected.  Nor is there any evidence that US transactions are, or can be, targetted with higher fees than transactions from other countries.  From some of the posts above, it looks like people are still buying into this FUD as fact.

This thread should be treated purely as a hypothetical 'what if?' scenario.  Not based in reality.  It isn't actually happening.  Nor is it ever likely to.
