What a digital asset is
A cryptocurrency is an entry on a distributed ledger. Ownership is established by control of a cryptographic private key rather than by a register kept at a company or a custodian. There is no issuer to call, no transfer agent, and no central record keeper who can correct a mistake.
That design is the point: it removes the need to trust an intermediary. It is also the source of nearly every practical difference that follows. A share register can be amended and a bank transfer can sometimes be recalled; a ledger entry cannot.
The assets named here differ widely in design and purpose, and treating them as one asset class hides more than it shows. What they share is the custody model and the absence of the protections described below.
How it differs from a share
| Aspect | Share or fund, compared with a digital asset |
|---|---|
| What you own | A share is a legal claim on a business, recorded on a register that can be amended. A digital asset is a ledger entry controlled by whoever holds the private key. |
| Underlying value | A share can be valued from a company's profits, assets and expected cash flows. Most digital assets produce no cash flow, so the price rests on what the next buyer will pay. |
| Custody | A regulated custodian holds a share in nominee name, with client assets segregated. For a digital asset, whoever controls the private key controls the asset. |
| Trading hours | Defined exchange sessions. Crypto markets run continuously, including overnight, when liquidity is thinnest. |
| Reversibility | A trade error can often be corrected through the broker. An on-chain transfer to the wrong address is permanent. |
| Protection | Investor compensation schemes cover firm failure in many jurisdictions. They usually do not extend to digital assets. |
Several rows have no equivalent on the digital-asset side. That is not a gap in the comparison: the structures that make a share recoverable after a mistake do not exist here.
Custody and private keys
This is the most consequential decision here, and it is usually arrived at by default rather than chosen.
- Custodial — an exchange or platform holds it
Convenient, and recoverable if you lose your password. It also rests entirely on that firm staying solvent and honest: you hold a claim against the platform, not the asset. Several large platforms have failed with customer assets attached.
- Self-custody — you hold the private key
No counterparty can fail on you and no platform can freeze your account. Equally, no one can help you. A lost key is a lost asset: there is no reset link and no support desk with an override.
- Hardware wallets
A device that keeps the key offline and signs transactions without exposing it. It cuts the risk of remote theft and adds the risk of a lost or damaged device where no recovery phrase is stored safely.
- The recovery phrase is the asset
Anyone who reads it can take everything. Never photograph it, type it into a website, store it in email or cloud notes, or share it with anyone claiming to be support. No legitimate party ever needs it.
Volatility and protection gaps
Digital assets are volatile and can fall sharply, including to zero. They are not covered by deposit guarantee schemes, and in most jurisdictions not by investor compensation schemes either. If a platform fails or a key is lost, there is usually no compensation and no route to recovery.
- Volatility is structurally higher. Moves that would be extraordinary in equity markets are routine here, and they arrive overnight, because the market never closes.
- Liquidity varies widely. Large assets trade deeply; smaller ones can be hard to exit at any sensible price, precisely when everyone wants out.
- Regulatory treatment is unsettled and country-specific. How an asset is classified affects what protections apply, how it is taxed, and whether a platform may serve you at all. It changes.
- Platform risk is concentrated. A custodial holding depends on one firm's solvency, security and honesty, often with far less segregation and audit than a regulated securities custodian.
- Fraud is common. Irreversible transfers and limited regulation make this a favoured channel for investment scams. The patterns are in the risk guide and the security guide.
Transfers are final
Sending a digital asset is closer to handing over cash than to making a bank payment. There is no recall process and no chargeback.
- Check the address. A transfer to a wrong but valid address is gone. Address-replacing malware is a known attack.
- Check the network. The same asset can exist on several networks. Sending on the wrong one commonly loses the funds, even when the address looks correct.
- Send a test amount first for any large or first-time transfer, and confirm receipt before sending the balance.
- Nobody legitimate asks you to send crypto. Not a tax authority, not the police, not your bank, not technical support, and not an investment adviser you met online.
Records and tax
Tax treatment varies by jurisdiction and it changes, so this is general information rather than advice. What holds broadly is that record-keeping is your responsibility, and harder here than for shares.
- Disposals are often taxable events — in many jurisdictions including a swap of one digital asset for another, not only a sale for currency.
- Spending can be a disposal. Buying something with crypto may trigger a gain calculation on the amount spent.
- Cost basis is yours to track. Platforms may not report it, and transfers between wallets break whatever trail a single platform holds.
- Keep records as you go. Dates, amounts, values at the time, fees and counterparties. Reconstructing years of activity afterwards is hard work.
One point on valuation. A disposal is usually recorded at the asset's value in your own currency at the moment of the transaction, not at the figure the platform displays today. For a swap between two digital assets, that means a currency value for both sides at the time — the record people find they do not have when a return falls due.
Frequently asked questions
Why do two platforms show different prices for the same asset?
Each platform prices from its own order book or from a different set of venues, and crypto markets trade continuously with no single official close. Differences widen when liquidity is thin, which is also when the quoted figure is least reliable.
What is a recovery phrase, and who should see it?
It is the human-readable form of the private key, and it is the asset. No one should ever see it. No platform, support desk, tax authority or wallet provider has a legitimate reason to ask for it, and anyone who reads it can move everything the key controls.
Is crypto protected like money in a bank?
No. Deposit guarantee schemes do not cover digital assets, and investor compensation schemes generally do not either. If a platform fails or a key is lost, there is usually no recovery route.
Should I keep crypto on an exchange or hold it myself?
Each moves the risk rather than removing it. An exchange can fail or freeze access; under self-custody, a lost key is a permanent loss with no support desk. The answer depends on the amount and on how confident you are about securing a recovery phrase.
I sent a transfer to the wrong address. Can it be reversed?
Generally no. On-chain transfers are final, and there is no central party able to reverse one. This is why a small test transfer before a large one is worth the delay.
