Bitcoin Gold is a cryptocurrency project forked from Bitcoin.
You can mine Bitcoin Gold, but the return is very low.
Bitcoin Gold has all the features that Bitcoin has. It runs on the Bitcoin network so transactions are very slow.
There is a scalability problem in Bitcoin Gold.
You don't need good computer hardware to make a good income from Bitcoin Gold mining. Adequate mining can be done with a normal computer. It is sufficient to have a low graphics card. If ordinary computers are not allowed to mine, I think the scalability problem will disappear. Bitcoin Gold uses the EQ algorithm.
Transactions made with Bitcoin Gold have low commissions. It is protected against price fluctuations and is little affected by manipulation. I don't think Bitcoin Gold is a suitable cryptocurrency to invest in.
The biggest problem with Bitcoin Gold is that it loads many transactions on a blockchain. Loading a large number of transactions on a chain causes slow transactions, decrease in efficiency and occasional non-execution of transactions.
