Currently, two of the most common digital assets are Bitcoin (BTC) and Ether (ETH).
What is Bitcoin?
Bitcoin is a cryptocurrency. It can be used to buy and sell goods and services from individuals or companies that accept Bitcoin as payment. It can be thought of as a digital currency that has no intermediaries, such as central banks, behind it. Like currency on foreign exchange markets, investors can also trade and invest in Bitcoin on cryptocurrency exchange markets. While there are many other such cryptocurrencies these days, Bitcoin was the first and as of June 2024 remains the largest. [5]
The idea of Bitcoin was first introduced in a whitepaper published in October 2008, under the pseudonym Satoshi Nakamoto. Nakamoto proposed a solution that would eliminate the need for trust in financial institutions such as central banks to issue and control money, and commercial banks to facilitate, execute and approve transactions. This was made possible through the creation of digital tokens called Bitcoin, to function as digital cash. All transactions of Bitcoin between users are recorded anonymously on a public “ledger” called the blockchain.
The Bitcoin network was launched on 3 January 2009, with a coin price of zero. Since then, Bitcoin’s trading history has been wildly volatile, fluctuating between peaks and troughs.
What is Ether?
Ether is the native cryptocurrency used on the Ethereum network. Ethereum is an open-source platform running blockchain technology that is used for creating decentralised applications known as DApps. The network's users can create, publish, monetise, and use applications on the platform.[6] Ether is the cryptocurrency required to use the Ethereum network.[7]
It's common to use Ethereum and Ether (ETH) interchangeably, but Ethereum is a blockchain network and Ether is used as the cryptocurrency to transact on Ethereum
What are the risks?
Crypto-assets can carry significant risk and there may be different risks to consider depending on the type of crypto-asset an investor buys and where it is bought. Investors should read all relevant materials and consider seeking professional advice before making any investment decision.
Key risks to consider when investing in crypto include, but are not limited to, the following:
- Crypto is largely not regulated: Many crypto-assets and other digital assets are commonly not considered to be financial products. In addition, the platforms where you buy and sell crypto may not be regulated. This means you may not be protected or have legal recourse if the crypto-asset issuer or exchange fails or is hacked.
- Highly speculative and volatile: Investing in crypto-assets is highly speculative. The market value can fluctuate a lot over short periods of time, and is affected by things like media hype and investor opinion. There may be little to no intrinsic value in the cryptocurrency and due to its technical complexity it can be hard to understand.
- Hacking, theft, and criminal activity: Thefts and cyber-attacks of crypto-assets can happen on exchanges where investors buy crypto or it can be stolen directly from the investors. Due to the unregulated nature of crypto, investors may have no recourse if this situation occurs. The use of crypto for illicit activity and scams can also have a negative impact on the reputation of cryptocurrencies.
- Technically complex: Crypto-assets can be hard to understand. There is usually no product disclosure statement or prospectus that explains clearly how the crypto works. Developers may issue a ‘whitepaper’ to describe it, but these can vary in format and information. A crypto-asset’s code may not be available to review. Or it may be written in obscure computing language. The underlying code of the crypto may also change over time. To access a crypto network, you may need special software and need to know how transaction fees operate. Unfamiliar users run the risk of:
- sending a transaction to an incorrect address
- over-paying on transaction fees called ‘gas’ (sometimes by thousands of dollars)
- not paying enough for a transaction fee (and so losing the fee and transaction)
- Environmental: Many crypto-assets require large amounts of energy consumption in order to operate. A material component of their energy usage is the proof-of-work consensus mechanism, a process undertaken by crypto-miners in order to achieve agreement, trust, and security across a decentralized computer network. While the energy-intensive nature of the proof-of-work process is leading to the creation of new and more efficient consensus mechanisms, such as proof-of-stake, at the time of writing Bitcoin and Ethereum both use proof-of-work.[8] In order to reduce their associated carbon emissions, crypto-asset miners are increasingly turning to renewable energy sources.
