Bitcoin vs. Bitcoin Cash: What’s the Difference and Which Is Better?

Bitcoin is the world’s most popular cryptocurrency, but it’s not without its problems. The nature of the technology makes it difficult to scale, and as a result, it’s nearly impossible for the average person to use BTC for everyday transactions like buying gas or milk.

Offshoots such as Bitcoin Cash have been developed as potential solutions to this problem, but to fully understand the differences between these options, it helps to know a bit about Bitcoin’s history.

Bitcoin

Bitcoin was created by Satoshi Nakamoto — an anonymous internet user or group working under a pseudonym — in 2009 on the back of the economic recession. It was presented as a form of peer-to-peer currency that didn’t rely on centralized banks.

While fiat currency is subject to spontaneous manipulation by governments, only a finite number of bitcoins will ever be available — 21 million. Until that maximum is reached, new coins are continually introduced to the market by a process called mining, in which powerful computers perform calculations that confirm the validity of transactions. As payment for use of their machines, miners collect fees on confirmed transactions, as well as the newly created bitcoins.

Although Bitcoin was meant to be used as digital cash, the volatility of the new cryptocurrency attracted investors while discouraging its use as legal tender.

The Scalability Problem

Concerns about Bitcoin’s limitations have been around since before the first block was mined. The very first public response to the original proposal expressed skepticism about its scalability: “The way I understand your proposal, it does not seem to scale to the required size.”

The reason is that the network is limited in how many blocks of transaction records can be processed in a given time frame because of the size limitations imposed by Bitcoin itself. New blocks are produced about every 10 minutes, and they’re limited to 1 megabyte in size.

As a result, the Bitcoin network has never managed to process more than eight transactions per second — a paltry figure next to the 1,700 TPS handled by a legacy payment network like Visa.

In an effort to solve this problem, developers introduced Segregated Witness — an upgrade that was developed in 2015 and is still in the process of being adopted networkwide.

SegWit works by separating the digital signature from the transaction info necessary to validate a transaction. Doing so reduces the effective transaction size, allowing more transactions to fit within a single block. SegWit represents a significant throughput upgrade because the signature often comprises up to 65% of a block. Freeing up all that space expands the effective block size from the original 1MB limit to around 4MB.

Bitcoin Cash

When a change to the Bitcoin protocol is proposed, it goes through an approval process by users and developers known as governance. In 2017, those participants came to a point of contention as to how they could solve the problem of scalability.

In the end, it came down to whether they should increase the actual size limit of each block or move some portion of, or even entire transactions to another layer, leaving only larger transactions to be settled on the base layer. Those in support of SegWit fell into the latter camp, contending that it was best to maintain the original 1MB limit.

On the other hand, a large enough number of users supported increasing the block size that they instituted a “hard fork” in the Bitcoin code, which emerged as a new currency altogether in the form of Bitcoin Cash. This move also started a new trend of forking the original Bitcoin project in order to create new cryptocurrencies, sometimes called split coins, without starting from scratch.

Bigger Blocks and Faster Transactions

Bitcoin Cash came with its own set of rules, including an increase of the maximum block size from 1MB to 32MB. This change drastically increased the speed at which transactions were processed, allowing BCH to process up to 200 transactions per second.

Additionally, the larger block size made space on blocks much less competitive, which decreased fees dramatically. Bitcoin fees average $4.40 per transaction, but they have reached heights of more than $60, according to BitInfoCharts. BCH fees, on the other hand, have never been more than $1 and have averaged 1.3 cents.

Bitcoin vs. Bitcoin Cash: A Difference of Philosophy

While BTC and BCH share some fundamental technology, they differ significantly in their philosophy.

Although Bitcoin was originally presented as a digital currency, people immediately saw it more as a way to make money. And while volatility is something that many cryptocurrencies share, Bitcoin seems to embrace its status as a store of value rather than a means of exchange. Its developers prefer to adhere to the tenets of decentralization and security first, while looking for ways to improve processing times as a secondary issue.

Conversely, Bitcoin Cash seeks first to make transactions fast and accessible with low fees, which is supposedly closer to the vision originally set forth by Nakamoto.

Interestingly, Bitcoin Cash has experienced its own set of hard forks for many of the same philosophical concerns that led to its own divergence from the original Bitcoin project.

Which Is Better?

The debate over whether Bitcoin will ever be accepted as a form of payment rages on, and there doesn’t appear to be an end in sight. Meanwhile, adoption of the original cryptocurrency as an investment continues to grow as investors hope to capitalize on its increased popularity.

Further, despite the slower transaction speeds, Bitcoin remains viable in cases where speed is less relevant, such as in real estate and automobile purchases. Additionally, major companies are adopting solutions to allow for everyday purchases using Bitcoin.

Bitcoin Cash, on the other hand, is relatively unknown outside of cryptocurrency circles, yet it remains the better option for near-instant transactions, especially for smaller amounts. Because the adoption level is still so low, it remains to be seen whether this is due more to the changes to the platform or the relative abundance of block space.

Takeaway

The bottom line is that these currencies represent different approaches to the digital future of finance. One places a greater focus on security, while the other emphasizes transaction speed and minimal fees. No one can yet be sure which is truly a better investment for the long term.
