Bitcoin Gold comes to be a fork of bitcoin itself, but it has not been very successful. At least it has managed to capitalize with funds in the Top 30 of the CoinMarketCap. Its popularization has been too slow, but it continues. However, there are other ways to obtain it. It is decentralized and also has a new mining scheme that seeks to benefit older users. Its objective is to democratize and decentralize the mining of cryptocurrencies, remember that mining is the process for the nodes to provide the operation and maintenance tasks in the network.
Highlights and important elements about Bitcoin Gold:
It has the Equihash working algorithm.
Adjustment in block difficulty after the addition of each block in the blockchain is done.
It has the same SegWit function as bitcoin.
It is placed the same as the original bitcoin in maximum offer.
Bitcoin Gold is an excellent opportunity to trade instead of a direct investment as such. Unfortunately it is a less successful option on the part of bitcoin involved in many controversies. My recommendation is that you carefully explore this cryptocurrency and take advantage of market movements so as not to make any mistakes.
