Bitcoin GPU, also known as Bitcoin GOLD and BGOLD with the symbol BTG, is planning to fork off the main chain and use an ICO to “help BTG chain the longest Bitcoin Blockchain.”
“Bitcoin GPU is a full node implementation of the Bitcoin protocol,” its website, which curiously features the Bitcoin Cash logo, states.
“GPU mining can protect Bitcoin Key value: Decentralize.”
The first Bitcoin fork, Bitcoin Cash, has become sufficiently widespread to warrant regulatory involvement from the US Securities and Exchanges Commission as Bitcoin holders received duplicates of their original BTC holdings.

Once forked from block number 478558, the assumption from commentators is that balances will double again, creating what trader Vortex refers to as “more free money.”
