Gold and Bitcoin are often compared as inflation hedges and stores of value. For UK investors, the comparison has a dimension most international sources miss: CGT treatment. Gold Sovereigns and Britannias are CGT-free. Bitcoin is not - every disposal is a taxable event.
This guide looks at the performance comparison, volatility, UK tax treatment, and what each actually is as an investment.
At a glance
| Gold (Sovereign) | Bitcoin | |
|---|---|---|
| GBP return 2021–2026 | ~+65% | ~-6% (highly variable) |
| CGT (UK) | Exempt (Sovereign/Britannia) | Taxable on every disposal |
| VAT | Exempt | No VAT |
| Regulated in UK | Not as investment | Partially - FCA crypto regime |
| Volatility | Moderate | Very high |
| Inflation hedge track record | Decades of data | Short history, limited evidence |
| Annual volatility (approx.) | 15–20% | 60–90% |
| Correlation with equities | Low | Moderate to high in recent years |
| Supply fixed? | No (mined) | Yes (21 million cap) |
Performance: 2021–2026
This comparison begins in 2021, near the point of Bitcoin’s peak enthusiasm.
Gold in GBP: Approximately £1,400/oz in early 2021 to approximately £3,800/oz by early 2026 - a gain of approximately 171% over five years.
Bitcoin in GBP: Approximately £42,000 at the January 2021 peak. Fell to approximately £12,000 in late 2022. Recovered to approximately £70,000+ by late 2024 before declining again. As of early 2026, approximately £39,000 - a five-year change of approximately -7% from the early 2021 peak.
Bitcoin owners who bought at different points have dramatically different outcomes - the entry point matters enormously. Gold buyers have had a more consistent experience regardless of entry point over this period.
Inflation hedge performance
Both gold and Bitcoin were marketed in 2021 as hedges against inflation. UK CPI peaked at 11.1% in October 2022.
Gold’s performance during the 2021–2023 inflation surge: Gold in GBP rose approximately 20–25% over the period 2021–2023, broadly tracking inflation in GBP terms.
Bitcoin’s performance during the same inflation surge: Bitcoin fell approximately 70% from peak to trough between November 2021 and November 2022 - the period of the highest UK inflation in 40 years.
On the specific test of the 2021–2023 inflation surge, gold performed its role. Bitcoin did not.
This does not definitively settle the question - Bitcoin proponents argue the relevant test is over a longer cycle, and Bitcoin’s longer-term supply characteristics (hard cap of 21 million coins) remain unchanged. The short history of Bitcoin means any single market cycle is limited evidence.
UK CGT: the major structural difference
This is the most consistently ignored part of the UK comparison.
Gold Sovereigns: All gains are CGT-exempt, regardless of size, holding period, or income level. No reporting required. No interaction with the CGT system.
Bitcoin: Every disposal is a taxable CGT event - selling for GBP, swapping for another cryptocurrency, or spending on goods and services. HMRC treats crypto as a chargeable asset. Gains are taxed at 18% (basic rate) or 24% (higher rate) above the £3,000 annual exempt amount.
Worked example:
| 10 Sovereigns | £9,400 in Bitcoin | |
|---|---|---|
| Purchase cost | £9,400 | £9,400 |
| Value at doubling | £18,800 | £18,800 |
| Taxable gain | £0 | £9,400 |
| CGT owed (higher rate, after £3k allowance) | £0 | ~£1,536 |
| Net gain | £9,400 | ~£7,864 |
The after-tax advantage of Sovereigns over Bitcoin increases as gains grow. At 5× appreciation, the gap is very large.
Volatility comparison
Gold’s annual standard deviation of returns is approximately 15–20% in GBP. Bitcoin’s is 60–90% in a normal year, with multiple 50–70% drawdowns in its history.
For investors using either as a portfolio hedge, Bitcoin’s higher volatility means smaller position sizes are needed to achieve the same risk contribution. It also means Bitcoin’s portfolio-stabilising properties during crises are unreliable - it has fallen sharply alongside equities in risk-off periods (notably March 2020 and late 2022).
Gold has maintained its non-correlation with equities during crises more consistently.
UK regulatory status
Gold: Buying and selling physical gold is not FCA-regulated. There is no FSCS protection for bullion dealers. Gold ETCs traded on LSE are listed instruments but not regulated as advisory products.
Bitcoin: The FCA has implemented a crypto asset registration and marketing regime. UK residents can only access crypto exchanges registered with the FCA. High-risk investment warnings are mandatory. The FCA does not regulate the underlying asset - it regulates the firms that distribute it to UK consumers.
Neither has meaningful investor protection from a regulatory standpoint. Gold has a longer established legal framework; Bitcoin’s UK regulatory environment is evolving.
Tax and regulation summary
Gold Sovereigns: CGT-exempt. VAT-exempt. Not FCA-regulated. No reporting on sale required.
Bitcoin: Every disposal is a CGT event. Gains reported via Self Assessment. No VAT on purchase or sale of crypto. Firms marketing to UK consumers must be FCA-registered.

How people usually decide
Investors who want a predictable, low-volatility hedge against currency depreciation and crisis risk tend to prefer gold. The track record is longer, the volatility is lower, and the UK tax position for Sovereigns is unambiguous.
Investors who believe in Bitcoin’s long-term thesis - fixed supply, increasing adoption, digital store of value - and can tolerate extreme volatility continue to hold it alongside or instead of gold. The two are not mutually exclusive.
The CGT difference is often the deciding factor for UK investors who have thought about it carefully. Gold Sovereigns’ CGT-free status is a structural advantage that compounds over time. See how to buy gold in the UK to get started.
Frequently asked questions
Is Bitcoin better than gold as an investment? That depends entirely on your time horizon, risk tolerance, and view of the future. Bitcoin has produced higher returns than gold over specific periods (notably 2019–2021). Gold has been significantly more stable and less correlated with equities during crises.
Are Gold Sovereigns CGT-free but Bitcoin is not? Correct. Gold Sovereigns are UK legal tender and CGT-exempt. Bitcoin is a chargeable asset - every disposal triggers CGT on any gain above the annual exempt amount.
Can I hold Bitcoin inside an ISA? Currently no. HM Treasury and HMRC do not permit crypto assets in ISAs. Gold ETCs can be held in ISAs. This is another structural tax advantage for gold over Bitcoin for UK investors.
Does Bitcoin have a fixed supply like gold? Bitcoin’s supply is capped at 21 million coins by protocol. Gold’s supply grows by approximately 1–2% per year through mining. Neither is genuinely “fixed” - Bitcoin because protocol changes are theoretically possible, gold because supply responds to price over long periods.
