Bitcoin Cash is the result of months of debate and development over how the currency would continue to evolve.
Fears of large swings in the value of Bitcoin have so far not been realised - but some exchanges are still adapting to the new currency.
One expert said the process had gone smoothly so far and pointed out that trade in Bitcoin Cash seemed "robust".
Bitcoin Cash was developed as a measure to increase the capacity of Bitcoin's underlying technology, the blockchain - a digital ledger that records every single transaction.
Bigger blocks
Because the old blockchain could only have one megabyte (MB) of data added to it every 10 minutes, transactions have come to be processed at slower rates.
Bitcoin Cash blocks can be as large as 8MB, which its proponents hope will help to solve this problem.
Yesterday, Bitcoin Cash was officially born when block number 478559 - at just under 2MB in size - was mined.
No major issues have so far been detected following the split although a few exchanges and wallets have had minor technical issues with supporting Bitcoin Cash initially, said Dr Garrick Hileman, research fellow at the Cambridge Centre for Alternative Finance.
