Nope, the longest valid chain is Bitcoin. Barry and Jihan (or anyone else) may make an invalid chain as long as you like it to be (EDA and ASICboost help too), but it will be ignored by economic Bitcoin nodes because it violates their governing consensus rules. No amount of drama can force Core nodes to accept invalid blocks, as we already know from enjoying the lulz provided by Bitcoin Scrypt, XT, Classic, Unlimited, Bcash, and most recently, Bgold.
BTC hash rate responds to economics. Within the incentive structure designed by Satoshi, as tx fees pile up and compete "inadequate" hash rate is a self-correcting problem.
Ironically, panic sellers help ameliorate the (exaggerated) problem of sluggish confirmations by paying higher fees to move coins for dumping ASAP.
Can't wait to see B2X #rekt by the same transaction fee markets the Gavinistas have spent years FUDing, ridiculing, distrusting, and trying to forcefully replace with a more centralized network...
Why wait until the rest of us may also be rolling gains into XMR? Adam Back is offering 3 B2X for 1 BTC right now. What a deal! Better act fast!
