Bitcoin (BTC) and Bitcoin Cash (BCH) are two well-known cryptocurrencies that share a common origin but differ in purpose and design. Bitcoin Cash was created in 2017 as a result of a hard fork from Bitcoin, mainly to address scalability and transaction speed issues.

Block Size and Scalability
The most significant difference lies in block size. Bitcoin’s block size is 1 MB, which limits the number of transactions processed per block. Bitcoin Cash increased this limit to 8 MB (and later even higher) to allow more transactions per block. This change helps Bitcoin Cash process payments faster and at a lower cost, making it more suitable for everyday transactions.

Transaction Speed and Fees
Bitcoin transactions can become slower and more expensive during network congestion. In contrast, Bitcoin Cash offers quicker confirmations and lower fees, appealing to users who prioritise fast, low-cost transfers.

Adoption and Purpose
Bitcoin focuses on being a store of value, often compared to digital gold. Bitcoin Cash, on the other hand, aims to function more as a medium of exchange for daily payments.

Conclusion
In summary, Bitcoin emphasises security, decentralisation, and value preservation, while Bitcoin Cash prioritises transaction efficiency and usability. Both serve different roles within the cryptocurrency ecosystem, appealing to investors and users with distinct goals.
