Just looking at some charts there looks like there's been some big movement on the network.
seems also the chain split has been detected!
BIP148 was supposed to split the chain - but seems to be turning into mostly a NONevent, as it's had pretty close to ZERO effect on Bitcoin network hashrate.
The only effect was that the FUD surrounding it seems to have caused Bitcoin PRICE to drop for a while (though the reported "exchange got hacked" might have been a bigger factor), and indirectly hurt the prices of many altcoins.
