After several years marked by sharp market swings, the boundary between traditional finance and digital assets has gradually become less distinct. Equities remain a cornerstone of long-term investing, while cryptocurrencies have established themselves in the financial landscape. Even so, combining the two is not simply a matter of adding Bitcoin to an equity portfolio. The key is to build a coherent asset allocation in which each asset class serves a specific purpose without throwing the overall risk profile out of balance.
Why combine equities and cryptocurrencies?
Before deciding how much to allocate to digital assets, it is worth taking the time to choose the right platforms for investing in crypto, particularly with regard to charges, security and the range of assets available. That exposure then needs to sit within a broader strategy: equities and cryptocurrencies have sufficiently different characteristics to play complementary roles within the same portfolio.
A share represents ownership in a company, and its value depends in particular on the business's activity, profits and prospects. ETFs, meanwhile, make it easy to spread an investment across dozens or even hundreds of companies. Cryptocurrencies work according to a different logic and remain far more volatile. It is precisely this difference that can make a blended allocation worthwhile, provided diversification is not mistaken for simply accumulating positions.
💡 Did you know?
Cryptocurrencies carry a risk of partial or total loss of the capital invested. Before investing, it is also important to check that the platform you choose is properly registered with or authorised by the Financial Conduct Authority (FCA), depending on its activities. The UK's new regulatory regime under the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 is expected to come into force on 25 October 2027.
How much should you allocate to crypto?
There is no ideal split between equities and crypto. It all depends on your investment horizon, your financial goals and, above all, your ability to cope with downturns. Digital assets can experience much sharper corrections than the main stock market indices. As a result, even a relatively modest allocation to crypto can have a meaningful effect on portfolio performance, both on the upside and the downside.
By way of illustration, here are three possible approaches to this allocation:
| Illustrative profile | Stock market | Crypto |
| Cautious | 98 to 100% | 0 to 2% |
| Balanced | 95% | 5% |
| Dynamic | 90% | 10% |
⚠️ These allocations are provided for illustrative purposes only and do not constitute investment advice.
Even limited exposure to cryptocurrencies can influence how a portfolio behaves. The greater their weighting, the stronger their impact on overall performance.
Diversify within each allocation
Diversification does not stop at the divide between equities and crypto. Holding a few technology shares alongside several cryptocurrencies may, for example, create the impression of variety while still leaving you heavily concentrated in higher-risk assets.
Each allocation should therefore be diversified according to its own logic:
- ✅ On the equity side, broad ETFs can spread exposure across many companies, several sectors and different geographical regions, rather than making the portfolio dependent on a small number of shares.
- ✅ On the crypto side, diversifying does not mean collecting tokens. Bitcoin can form the core of this exposure, potentially complemented by Ethereum, while smaller assets generally have a more speculative profile.
The advantage of this kind of structure is that it also keeps the portfolio easy to understand. Adding more and more lines does not necessarily improve diversification. The aim remains to prevent any single company, sector or cryptocurrency from throwing the entire portfolio off balance on its own.
Invest gradually and rebalance
Choosing an allocation is a first step; maintaining it over time is another. Investing gradually, for example by contributing a fixed amount at regular intervals, reduces dependence on the entry point. This method, often referred to as DCA (Dollar Cost Averaging), does not, of course, protect against falls, but it does prevent the whole strategy from hinging on trying to find the "right" moment to invest.
Rebalancing then plays an essential role. Imagine a portfolio initially made up of 90% equities and 10% cryptocurrencies. After a strong rise in the crypto market, that allocation might come to represent 20% of the whole. Returning towards the original allocation helps keep risk exposure under control and ensures you remain faithful to the strategy set at the outset.
This discipline also prevents market movements from gradually determining the portfolio's composition for you. An allocation designed for the long term is not meant to be turned upside down by every bout of market volatility.
Finding the right balance between return and risk
Combining equities and cryptocurrencies can broaden a portfolio's sources of performance, but diversification only truly comes into its own when it also helps manage risk more effectively. The main point, then, is not to multiply the number of holdings, but to determine how much weight each asset class should carry and to maintain a degree of discipline over time.
Ultimately, a well-diversified portfolio is one whose risks you understand and that you are able to stick with when markets become more turbulent.
