Digital assets explained

What are digital assets?

A digital asset is something of value that exists only as a digital record. In everyday use, the term usually means assets recorded on a blockchain: a shared ledger that many computers keep in step, so that no single company or government controls the record of who owns what.

Cryptocurrency is the best-known kind. But the category is broader than coins. It includes stablecoins designed to track a national currency, tokens that represent a share of a real-world asset, and networks that run programs as well as recording payments. Each has a different purpose and a different set of risks, which is why it helps to learn them one at a time.

Bitcoin: digital money with a fixed supply

Bitcoin was launched in 2009 as a way to send value over the internet without a bank in the middle. Its software caps the total supply at 21 million coins, and anyone can check the public record of transactions. New coins are released on a schedule that slows over time.

That fixed supply is the centre of most debates about Bitcoin. Supporters compare it to digital gold. Critics point to its short history, its heavy price swings and its lack of income such as interest or dividends. Its price has fallen by more than 70% more than once. Our page on inflation and savings looks at where that supply cap fits in the wider conversation about money.

Ethereum and programmable networks

Ethereum is a blockchain designed to run programs, often called smart contracts, as well as record transfers. Its own currency, ether, pays for the computing work the network does. Many other tokens, applications and stablecoins are built on top of it.

Programmable networks open up new uses, but they also add new kinds of risk. A flaw in a smart contract can be exploited, and the more complex a product is, the harder it is to understand what could go wrong.

Stablecoins

A stablecoin is a token designed to hold a steady value, usually one US dollar. Most are backed by reserves such as cash and short-term government debt held by the company that issues them. People use them to move money between platforms or to step out of more volatile assets without leaving the digital asset system.

“Stable” describes the aim, not a promise. A stablecoin depends on the quality of its reserves, the honesty of its issuer and the rules it operates under. Some have lost their link to the dollar entirely.

Tokenised assets

Tokenisation means recording ownership of a traditional asset, such as a fund, a bond or a share in a property, as a token on a blockchain. The appeal is faster settlement and the ability to own smaller pieces of large assets. The token is only as good as the legal arrangements behind it, so the questions about who holds the underlying asset, and what rights the token really gives, matter as much as the technology.

Self-custody and exchanges: who holds the keys

Owning a digital asset really means controlling the private key that can move it. You can leave that key with an exchange or custodian, much like leaving money with a bank, or hold it yourself in a wallet. In Australia, exchanges that swap digital currency for money must register with AUSTRAC, but registration is not a guarantee that a business is sound.

Holding your own keys removes the risk of an exchange failing or freezing withdrawals. It adds a different risk: if the key or its backup is lost, there is usually no one who can restore it. Our free guides cover the basics of keeping digital assets secure, and our page on digital assets and family legacy explains why access matters so much when assets pass to the next generation.

The risks of digital investment

Digital assets are high-growth, high-risk assets. Before anyone treats them as part of their long-term thinking, it is worth understanding the main risks clearly:

• Volatility: prices can rise or fall sharply in a short time, and past movements say nothing reliable about the future.
• Loss of access: lost keys, forgotten passwords and failed backups can mean permanent loss.
• Platform failure: exchanges and lenders have collapsed, leaving customers unable to withdraw.
• Scams: fake investment schemes, impersonation and pressure tactics are common.
• Rules and tax: regulation is still changing, and in Australia the ATO generally treats disposals of crypto assets as events for capital gains tax.

How people learn about cryptocurrency

The most useful starting point is usually slow and unglamorous: understand what money is, how each asset works and what can go wrong, before thinking about any decision. Our course pathway starts with Bitcoin foundations and moves on to long-term and legacy planning. Our free tools let you play out scenarios with your own numbers, and the book tells the longer story of money from shells to Bitcoin.

If you advise clients, our page for financial professionals explains how the same material can help you get up to speed. If you run a self-managed super fund, see digital assets and SMSFs.

Questions people ask about digital assets

Is cryptocurrency the same thing as a digital asset?

Cryptocurrency is one kind of digital asset. The wider term also covers stablecoins, tokenised versions of real-world assets and other records of ownership kept on a blockchain.

Why does Bitcoin have a 21 million coin limit?

The limit is written into Bitcoin's software, and changing it would need the network's participants to agree. Supporters see it as a strength. Critics point out that scarcity alone does not give anything a stable value.

Are stablecoins free of risk?

No. A stablecoin is only as reliable as the reserves and the organisation behind it, and some have lost their link to the currency they were meant to track.

What does self-custody mean?

Self-custody means you hold the private keys to your digital assets yourself rather than leaving them with an exchange. It removes reliance on a third party but puts all of the responsibility for security and backups on you.

Is digital investment suitable for everyone?

Digital assets are high-growth, high-risk assets and are not suitable for everyone. Whether they suit your situation is a question for a licensed financial adviser, not a general education website.
