So Bitcoin Gold forked with minimal fireworks...
It technically hasn't even launched yet. They just now have the UTXO/blockchain snapshot that they want.
Coinbase also announced that segwit2x will be call B2X on thier platform. Does the segwit2x update create a new coin?? Why is Coinbase labeling it at B2X?
Segwit2x is a hard fork, so it will create an altcoin.
