Bitcoin Cash appeared in early August when a group of developers created a separate version of the Bitcoin blockchain, so that more transactions could be processed at a faster rate, with lower associated fees involved.
When news of a potential split or "fork" in the blockchain first appeared, Coinbase said it would not support trading in the new currency that would be created as a result, but in August it reversed its decision and said customers would be able to withdraw Bitcoin Cash from the first day of 2018.
Following today's app update, all users will be credited an amount of Bitcoin Cash that is equal to their Bitcoin balance when the fork occurred on August 1. Bitcoin Cash trading will also be available on GDAX, which is Coinbase's institutional-based exchange.
The Coinbase app surged to the top of Apple's free apps chart in the App Store last week, amid a speculative frenzy surrounding the blockchain cryptocurrency. Today's announcement that it would support Bitcoin Cash caused BTC to drop sharply in the early hours as users switched currencies, but the value appears to have stabilized since, at around $17,599 as of writing.
Also this week, a new version of the CoinHub app was released. Version 1.5 of the cryptocurrency quote platform brings a new secure portfolio, Reddit and news separation, fresh UI styling, and a FOREX engine that lets users purchase any currency pair and automatically see the value in their local fiat currency.
