A new version of Bitcoin has been made for the first time in crypto-currency history.
Bitcoin Cash is the result of months of debate and development on how the currency will continue to evolve.
The fears of major changes in Bitcoin's value so far have not been realized - but some exchanges are still adapting to the new currency.
An expert said the process had gone well so far and noted that Bitcoin Cash trade looked "powerful".
Bitcoin Cash developed as a measure to increase Bitcoin's basic technology known as blockchain - a digital book that records every single transaction.
"A market seems to be developing for Bitcoin Cash that seems to be relatively powerful," said Dr Garrick Hileman, a researcher at the Cambridge Center for Alternative Finances, for the BBC.
Fresh crypto-coins traded over $ 400 (£ 300) over 12 hours after its creation.
Bitcoin itself saw a modest decline in price Tuesday, but was still over $ 2,700 (£ 2,000) at 10:00 BST on Wednesday.
