Capital at risk. Cryptoassets are highly volatile and can lose most or all of their value. The UK Financial Conduct Authority says that if you invest in crypto "you should be prepared to lose all your money". This is general information, not personalised advice.
For most investors who want any crypto at all, a small slice — around 1% to 5% of the portfolio, and nothing you could not afford to lose entirely — is the defensible range. The most widely quoted institutional benchmark, from the BlackRock Investment Institute, puts a reasonable bitcoin allocation at around 1–2% for institutions that believe in its widespread adoption, because larger positions take up a disproportionate share of portfolio risk. The right number for you is set by how big a fall you could live with, which the table below lets you work out.
Start from the loss you can accept
The simplest way to size a crypto position is backwards: decide how much of your total portfolio you could lose without changing your plans, then divide by how far crypto could fall. Falls of that size have happened: BlackRock noted in August 2026 that bitcoin had "pulled back roughly 50% from its October 2025 highs". The table tests a deeper 75% fall.
Worked example: a 100,000 portfolio, testing a 75% crypto fall.
| Crypto allocation | Amount in crypto | Loss if crypto falls 75% | Loss as % of whole portfolio |
|---|---|---|---|
| 1% | 1,000 | 750 | 0.75% |
| 2% | 2,000 | 1,500 | 1.5% |
| 5% | 5,000 | 3,750 | 3.75% |
| 10% | 10,000 | 7,500 | 7.5% |
| 20% | 20,000 | 15,000 | 15% |
If a 3.75% hit to the whole portfolio would make you sell everything, 5% is too much for you. If losing the entire crypto amount — not just 75% of it — would derail a goal, the allocation is too high regardless of what anyone recommends.
What institutional research says
BlackRock's December 2024 paper Sizing bitcoin in portfolios uses a risk-budgeting approach: it sizes the position by how much it adds to total portfolio risk. Its conclusions:
In August 2026, after the drawdown mentioned above, BlackRock's follow-up Re-Underwriting Bitcoin repeated that "a modest 1–2% allocation to bitcoin would have improved risk-adjusted returns in a traditional 60/40 portfolio". Note what that is: a statement about the past, from a firm that also sells bitcoin funds, aimed at institutions. It is a useful upper reference point for a cautious investor, not a forecast.
Three common sizing approaches
| Approach | Typical range | Who it suits | The trade-off |
|---|---|---|---|
| Token | Under 1% | Curious, or unconvinced but want a stake | Barely moves the portfolio either way |
| Benchmark | 1–2% | Want exposure sized like a single large share | A total loss still costs 1–2% of the whole |
| Higher conviction | 5% or more | Long horizon, emergency fund in place, no expensive debt | A severe fall is clearly visible in the total; the risk share rises much faster than the weight |
Above 5%, the risk crypto contributes grows much faster than its weight, as the BlackRock chart shows for a 4% position. Anyone going that high should be doing so deliberately, after the loss test above.
What to hold within the allocation
A common split is mostly bitcoin with a minority in ether; holding only bitcoin is simpler. Neither is a recommendation.
Where to hold it
| Option | How it works | Main risk |
|---|---|---|
| Exchange account | The exchange holds the coins for you | The exchange failing, freezing withdrawals or being hacked; balances are not deposit-protected |
| Hardware wallet | You hold the private keys yourself | Losing the recovery phrase means losing the coins |
| Exchange-traded product in a brokerage account | You own fund shares that track the price | Fund fees and tracking; available products depend on your country |
The trade-offs between self-custody and leaving coins on an exchange are set out in crypto cold storage vs exchange custody. In the UK, the FCA says crypto investors are "highly unlikely" to be covered by the Financial Services Compensation Scheme.
If you would rather hold the assets directly, a large regulated exchange such as Bybit or Coinbase is where most investors buy and custody smaller allocations — availability varies by country, so check that the platform operates where you live, and remember that capital is at risk and exchange balances carry no deposit protection. Investors who want their satellite allocation to generate income as well as price exposure can also earn interest on part of it; we cover the trade-offs in our crypto yield guide and our review of Bybit Earn.
Rebalancing: why the allocation will not stay put
Because crypto moves so much more than shares and bonds, its weight drifts quickly.
Worked example: you start with 95,000 in a share-and-bond portfolio and 5,000 in crypto (5%). If crypto triples while everything else is flat, it is worth 15,000 out of 110,000 — 13.6% of the portfolio, nearly three times the risk you chose. Rebalancing back to 5% means trimming crypto to 5,500 and moving 9,500 into the rest. If instead crypto falls 60%, it is worth 2,000 out of 97,000 — 2.1% — and topping it back up means buying after a fall.
Set the rule in advance — for example, rebalance once a year, or whenever crypto moves outside 3–7% on a 5% target — so the decision is not made in the middle of a rally or a crash. Rebalancing may trigger tax on gains, depending on where you live. The general method is in rebalancing your portfolio.
Frequently asked questions
What percentage of my portfolio should be in crypto?
For most investors, between nothing and about 5%, sized so that losing the whole amount would not change your plans. BlackRock's institutional research suggests around 1–2% in bitcoin could be reasonable for investors who believe in its widespread adoption, and warns that larger positions skew portfolio risk.
Is 10% in crypto too much?
For most people, yes. On a 100,000 portfolio, a 75% crypto fall at a 10% allocation costs 7,500, or 7.5% of the whole. BlackRock's analysis shows even a 4% bitcoin position accounting for about 14% of a 60/40 portfolio's risk.
Should I hold only bitcoin, or other coins too?
Holding only bitcoin is the simplest approach, and it is the asset the BlackRock research covers. Adding ether is a separate bet on the Ethereum network. Smaller tokens carry much higher risk of failure and should be a small part of any crypto slice.
How often should I rebalance a crypto allocation?
On a rule set in advance: once a year, or when the weight drifts outside a band such as 3–7% on a 5% target. Without a rule, a rally can quietly turn a 5% position into more than 13%.
