Bitcoin Gold (BTG) is a cryptocurrency that was created in 2017 as a hard fork of the original Bitcoin blockchain. The main aim of BTG was to make mining more accessible to the average person by using a different mining algorithm that could be run on standard computer hardware. This was in response to the increasing centralization of Bitcoin mining, which was becoming dominated by large mining pools and specialized hardware. BTG uses the Equihash algorithm, which is designed to be resistant to ASIC mining, meaning that it can be mined using standard GPUs. This makes it more accessible to a wider range of people and helps to decentralize the mining process.

BTG has a total supply of 21 million coins, which is the same as Bitcoin. It has a block time of 10 minutes and a block reward of 12.5 BTG, which halves every 210,000 blocks. BTG has a number of features that are similar to Bitcoin, such as its decentralized nature and its ability to be used as a store of value or a means of payment. However, it also has some key differences, such as its mining algorithm and its focus on decentralization. Overall, BTG is an interesting cryptocurrency that offers some unique features and could be a good investment opportunity for those who believe in its potential.
