[bitcoin-dev] A reason we can all agree on to increase block size

Increasing the block size shouldn't be a problem for Chinese miners.
Five of the largest - F2Pool, Antpool, BW, BTCChina, Huobi - have
already signed a draft agreement indicating they are fine with an
increase to 8 MB: http://www.8btc.com/blocksize-increase-2

With regards to China's international bandwidth, not only is intra-Asia
capacity improving all the time, a major consortium cable FASTER is
coming online Q2 2016.  Backed by Google, China Telecom and others, it
has a capacity of 60 Tbps, making it the highest-capacity data link ever
created across the Pacific.
