By the time Blockchain Bitcoin 491,407 blocks, a new protocol version will be formed. The result is a Bitcoin replication coin called Bitcoin Gold (BTG).
Pros
BTG will be dug with GPU (video card instead of CPU of ASIC)
BTG will support the Replay Protection technology (Restrict confusion when exchanging Bitcoin)
BTG will change difficulty in each block chain
Cons
This comes after the BTG team flip-flopped several times, first saying they were, and then they weren’t, going to be pre-mining BTG. This marks a significant breach of trust.
