well, it's a good news for you since you are mining btc.

As for btc as a whole, I don't have a clear reasoning why but my gut says something bad is happening to btc... Why throw away a perfecting functioning source of pure GDP producer?? Assuming china is not crazy and are rational to some degree, they must think doing so will be much more profitable. Perhaps they will use all that mining rigs to mine some new coin that is more profitable or promising. idk.
