Even though their names are the same, Bitcoin (BTC) and Bitcoin Cash (BCH) are two different digital currencies. This makes some people wonder: How do you use Bitcoin Cash? Bitcoin Cash is meant to be a digital currency that can be used to buy things and pay for things. It’s meant to fix Bitcoin’s “scalability problem” and make it more useful in everyday life. It’s not meant to be kept as a store of value, but to be spent. The main difference between BCH and BTC is that BCH’s native blockchain has larger blocks. This makes BCH transactions much faster and cheaper to complete.
