Bitcoin and ethereum are the two biggest cryptoassets by market cap today, worth a combined total of just over £1.1 trillion. Yet each crypto is valuable in its own different way.
Bitcoin has been designed to be an anti-inflation cryptoasset, with its total possible supply of 21 million bitcoins intended to make its price rise as more people buy and hold the cryptoasset.
Ethereum, on the other hand, is what’s known as a ‘utility token’. This means it’s used to pay for transactions on its blockchain, which runs a growing number of applications and platforms.
It is because of the various functions of different cryptos that it is in fact inaccurate to refer to them all under the blanket term ‘cryptocurrencies’. Out of all cryptoassets out there, only some are currencies.
Because of this contrast in use cases, bitcoin and ethereum aren’t really rivals. Investors may therefore want to consider allocating some of the crypto part of their portfolios to both, since they have risen and could continue to rise in price together.
Bitcoin and ethereum are the two main cryptoassets with the largest market caps
Bitcoin is the world’s first ever cryptoasset. Outlined by the pseudonymous Satoshi Nakamoto in a 2008 whitepaper, it was launched in January 2009.
What makes bitcoin unique compared to earlier attempts at electronic money is that it uses a blockchain to record its transactions. This is a type of shared database that prevents users from changing or removing its data once this data has been entered.
Having a feature like this helps combat fraud and white collar crime because the authenticity of a transaction can be verified and confirmed.
Bitcoin initially attracted only a small number of investors, who were intrigued by the fact that it operated without the involvement of a central bank or any other centralised organisation.
Another key feature of bitcoin is that it has a maximum possible supply of 21 million bitcoins. Its current supply sits at just under 19 million, with new bitcoins being ‘mined’ with every new block of transactions produced.
Mining refers to the computational process of verifying transactions on bitcoin’s blockchain. This is done by people or (increasingly) companies using powerful computing hardware, with so-called miners rewarded with 6.25 bitcoin for every block they confirm first.
Ethereum was launched in 2015 by a team of developers led by Russian-Canadian programmer Vitalik Buterin, who had been interested in bitcoin for several years.
Ethereum is a cryptoasset much like bitcoin, in that it can be traded. However, unlike bitcoin, it was designed for a different set of uses and has a theoretically unlimited supply.
It also runs on its own blockchain, which Buterin and his co-founders intended as a ‘world computer’ capable of running any kind of computer application.
The key innovation of its blockchain is that it can run smart contracts, which are contracts that self-execute whenever certain conditions are met.
For example, if one person sends another some information using ethereum’s blockchain, a smart contract can be set up so that ethereum is automatically sent as payment to the first person upon receipt of the info.
The bitcoin price in US dollars over the past five years: Since 2016, bitcoin’s price has boomed sunk and then boomed again to hit a record high in November – it was a third on that point at $48,900 on 16 December 2021. Past performance is not an indication of future results.
Investors now hold bitcoin and ethereum for contrasting reasons.
With bitcoin, its limited supply means that growing numbers of investors view it as a hedge against inflation, which is currently rising in the UK, the US and elsewhere.
Record-low interest rates have also made it increasingly attractive to people and institutions with capital to invest.
After being virtually worthless on its launch in 2009, bitcoin’s price gradually rose to $1 in 2011.
It reached as high as $1,242 by November 2013. It then suffered a decline following the collapse of the Mt. Gox crypto-exchange, which most investors at the time used to buy and sell crypto.
After sinking as low as $220 in the summer of 2015, it began a gradual recovery to the $1,200 level by the start of 2017. It then rallied strongly at the end of 2017 to nearly $20,000, becoming known among much of the general public for the first time.
Bitcoin is volatile, however, and after 2017 its price suffered another two years of decline. Then it began rising again towards the end of 2020, reaching a series of all-time highs into 2021.
Its current record high is $69,000, set on November 10, but since then the price has fallen a third to $48,900 on 16 December 2021.
While the cryptoasset’s limited supply may suggest that its price should rise in the long-term, potential investors need to be aware that it has followed a boom-and-bust cycle in the past.
Ethereum’s path to adoption hasn’t been quite as dizzying as bitcoin’s, but is still impressive.
It was worth about $1 upon its launch in 2015, and rose as high as $1,400 in January 2018. It then suffered a two-year decline along with bitcoin, before reaching a new series of record highs in 2020 and 2021.
Its current all-time high is $4,878, also set on November 10, since then it has fallen 17 per cent to just above $4,000 on 16 December 2021.
Ethereum has attracted investors not as an inflation hedge, but because it’s the most widely used blockchain platform capable of running smart contracts.
Thousands of different apps and platforms run on its blockchain, and together these applications hold cryptoassets worth just over £130 billion.
The ethereum price in US dollars over the past five years: Ethereum has followed a similar pattern to bitcoin’s since 2016 and also hit a high in November but it has fallen by less since, with a decline of 17% to just above $4,000 on 16 December 2021. Past performance is not an indication of future results.
The reason why use of Ethereum’s blockchain boosts its value is that the cryptoasset is needed to pay transactions fees.
So, if someone wants to use one of the many applications running on its blockchain, they will need to pay an amount of ethereum. This amount can vary according to user traffic.
Given that Ethereum’s blockchain processes over one million transactions per day, this results in significant demand for the cryptoasset.
The more it grows as a platform, the more demand there will be for ethereum, and the more – all other things being equal – its price could rise.
Ethereum’s developers are planning an important upgrade for next year. This will see it change the mechanism by which it confirms transactions, with the people who do the confirming – called ‘validators’ – having to stake ethereum to verify a new block of transactions.
Staking is holding a certain amount of the cryptoasset to participate in ethereum’s blockchain network and gaining ether as a reward for partaking. Staking will take millions of ethereum out of circulation, making the cryptoasset scarcer and – in theory – more valuable.
The upgrade will also enable ethereum’s blockchain to process as many as 100,000 transactions per second, in contrast to the maximum of 30 per second it can handle now.
This should make it more desirable to developers, with its blockchain currently hosting around 2,889 apps, from video games and social networks to crypto-exchanges and crypto-based lending platforms.
Once it makes this transition, this tally of apps could increase rapidly, and with it so too could ethereum’s price.
Bitcoin and ethereum are big contenders within the crypto ecosystem, and both can have their place within a diversified crypto portfolio.
Bitcoin has become the default crypto asset and is considered by some to be akin to digital gold, while ethereum is viewed by some as a building block for the digital future.
Many crypto investors hold both bitcoin and ethereum and have different investment cases for each. For those interested in investing in crypto it is worth considering them both on their individual merits.
