For instance, paying for a sandwich or a cup of coffee with BTC just simply wasn’t viable, as a $3 cup of coffee will incur a transaction fee of more than $15. Otherwise, the seller will receive an unspendable dust amount.
Bitcoin Cash was a different story. It differs from the other versions in that in enabled the increase of the block size from one MB to eight MB. It’s overall goal is to increase the number of transactions that can be processed by the network, hoping that Bitcoin Cash will be able to compete with the volume of transactions that industry giants like PayPal and Visa can currently process.

Workgroups have been set up to assist developers to coordinate and seek peer-review. For those wishing to implement changes to the Bitcoin Cash protocol, it is recommended to seek early peer-review and engage collaboratively with other developers through the workgroups.
Like email, bitcoin is a protocol. Where email is a protocol for sending messages over the internet, bitcoin is a protocol for sending money over the internet. The bitcoin protocol defines the rules of a payment network, called bitcoin, that uses a currency, also called bitcoin, to pay computers around the world for securing the network. The software that implements the bitcoin protocol uses a special branch of mathematics called cryptography to ensure the security of every bitcoin transaction.
