According to ChainCatcher, the chain forked from Bitcoin on August 8, and its native token BTCB2 has been labeled by some trading platforms as Bitcoin BLAKE2b, Bitcoin BIP-110, or XBT. BTCB2 has fallen 84% from its September high of $1,799 and was trading at about $270 to $315 in recent hours. Developer Luke Dashjr said some BLAKE2b mining pools are “attacking” the network.
