Cryptocurrency has become an increasingly common part of the investment conversation, but deciding how much to allocate in your portfolio is less straightforward.
Crypto can offer significant growth potential, but it can also experience much larger price swings than traditional investments such as shares and bonds. That means the right allocation depends on your circumstances, your attitude to risk and what you are trying to achieve with your wider portfolio.
There isn’t a single percentage that works for everyone. Instead, it helps to think about where crypto fits within your overall investment strategy and how much risk you are comfortable taking.
Start with your overall portfolio
Before deciding how much crypto to own, look at your investments as a whole.
A diversified portfolio might include assets such as:
Shares
Bonds
Cash
Property
Funds or ETFs
Commodities
Cryptocurrency
The purpose of diversification is to avoid relying too heavily on one type of investment. Different assets can behave differently in changing market conditions, although diversification cannot eliminate investment losses.
Crypto should therefore be considered as one part of a wider portfolio rather than as a replacement for your other investments.
For example, someone who already has most of their money invested in shares may have a very different risk profile from someone whose savings are mostly held in cash. The same crypto allocation could have a very different impact on each portfolio.
How much crypto is appropriate?
There is no universally correct crypto allocation.
Some investors choose to have no exposure to cryptocurrency at all. Others may allocate a small percentage of their portfolio, while investors with a higher tolerance for risk may choose a larger allocation.
The important point is that the percentage should make sense within your own financial plan.
One useful way to think about this is to consider how you would react if the value of your crypto holdings fell substantially. If a significant fall would cause you to panic and sell other investments, your allocation may be too large for your risk tolerance.
On the other hand, if you understand the risks and are comfortable with crypto making up a relatively small part of your overall investments, a modest allocation may be easier to manage.
The number itself matters, but so does the effect that number would have on your behaviour.
Consider your risk tolerance
Risk tolerance is essentially how much investment loss and price volatility you are comfortable with.
Cryptocurrency can be particularly volatile. Prices can rise or fall sharply over relatively short periods, and individual cryptocurrencies can be considerably more volatile than the broader market.
Before investing, consider questions such as:
How would I feel if my crypto investment lost 20% of its value?
What about 50%?
Would I need the money in the next few years?
Am I investing for a long-term goal?
Would a large fall affect my ability to meet that goal?
Am I comfortable holding through periods of significant volatility?
Your answers can help put the potential allocation into perspective.
Risk tolerance is also different from risk capacity. You might be comfortable with a large amount of volatility emotionally, but that does not necessarily mean you can afford to take that level of risk financially.
Think about your investment timeframe
Your investment timeframe matters when deciding how much risk to take.
Money that you expect to need soon is generally treated differently from money that you are investing for a much longer-term goal.
If you are saving for something that is only a year or two away, a large exposure to an asset that can experience substantial short-term price movements could create a problem if the market falls when you need to withdraw the money.
Longer-term investors may have more time to deal with periods of volatility; however, a longer timeframe does not remove the risk of losing money.
This is why crypto allocation should be considered alongside the purpose of your investments.
Don’t confuse diversification with owning lots of cryptocurrencies
Owning several different cryptocurrencies does not automatically mean you have a well-diversified portfolio.
If most of your investments are still concentrated in cryptocurrencies, you may have diversified within one asset class without actually diversifying your overall portfolio.
For example, holding Bitcoin, Ethereum and several smaller cryptocurrencies gives you exposure to multiple digital assets, but they can still be affected by many of the same market forces.
True portfolio diversification looks across different types of assets and investments.
This does not mean that every portfolio needs to contain a long list of investments. In fact, owning too many assets can make it harder to understand what you actually own and why you own it.
Think about crypto within your wider asset allocation
Once you have considered your risk tolerance and investment timeframe, look at how a crypto allocation would affect your overall asset mix.
For example, suppose someone has a portfolio worth £20,000 and decides that they are comfortable allocating 5% to cryptocurrency. That would give them £1,000 of crypto exposure, with the remaining £19,000 invested elsewhere.
If the crypto allocation later doubled while everything else stayed the same, crypto would make up a larger percentage of the portfolio. The opposite could happen after a significant fall.
This is why portfolio allocation is not necessarily a decision you make once and forget about.
Rebalancing can keep your portfolio on track
Rebalancing means adjusting your investments when your actual allocations move away from your intended targets.
Imagine an investor initially allocates 5% of their portfolio to crypto. If crypto subsequently performs very strongly, it could grow to represent 10% or more of the portfolio.
The investor then has a choice. They could leave the allocation where it is, or they could sell some of the crypto and move the money into other investments to bring the portfolio closer to their original allocation.
The reverse could happen after a market decline.
There is no guarantee that rebalancing will improve investment returns, and selling or buying investments can also have tax implications. The important point is that having a target allocation gives you a framework for making these decisions rather than simply reacting to market movements.
Use a portfolio calculator to model different allocations
It can be difficult to understand what a particular percentage actually means when you are looking at a portfolio as a whole.
A crypto portfolio calculator can help you model different allocations and see how much of your total portfolio would be represented by cryptocurrency alongside your other investments.
For example, you could compare what a 2%, 5%, or 10% crypto allocation would look like based on your current portfolio size. This doesn’t tell you which allocation you should choose, but it can make the numbers easier to understand.
You can use the Crypto Portfolio Calculator to model different portfolio allocations before deciding how you want your investments to be structured.
Don’t let crypto become your entire investment strategy
One of the biggest mistakes an investor can make is allowing an individual investment to become the entire focus of their portfolio.
Crypto can be an interesting part of a broader investment strategy, but it is still only one asset class. Your wider financial position, emergency savings, pension, other investments and financial goals all matter when deciding how much risk to take.
It’s important to remember that past performance does not guarantee future results. A cryptocurrency that has performed strongly in the past may not continue to do so.
The same principle applies to the wider investment market.
So, how much crypto should you have?
There is no universal answer.
The appropriate allocation depends on factors including your risk tolerance, investment timeframe, financial circumstances and the rest of your portfolio. For some people, that could mean having no crypto exposure. For others, it could mean allocating a small proportion of their investments to digital assets.
Rather than starting with a target percentage and trying to make your portfolio fit around it, start with the bigger picture.
Understand what you are investing for, assess how much risk you can afford to take, look at your existing asset allocation and then consider whether crypto has a sensible place within it.
The goal is not necessarily to find the perfect percentage. It is to build a portfolio that you understand and can stick with when markets become difficult.
Frequently Asked Questions
Can I lose all my money investing in cryptocurrency?
Yes. Individual cryptocurrencies can fall dramatically in value, and some crypto projects have failed. Unlike cash held in a bank account, cryptocurrency investments are not protected by the Financial Services Compensation Scheme. This is one reason why crypto should only represent an amount you are comfortable losing.
Should I invest in crypto before paying off debt?
High-cost debt, such as credit card balances, can be an important consideration before investing in volatile assets. The interest charged on existing debt may outweigh the potential return from an investment. It is sensible to consider your debts, emergency savings and other financial commitments before allocating money to crypto.
Should I invest in Bitcoin or several cryptocurrencies?
Investment strategies may differ from investor to investor; there is no one-size-fits-all approach. Holding several cryptocurrencies can spread your exposure across different digital assets, but it does not necessarily create the same diversification as investing across different asset classes. If you choose to invest in multiple cryptocurrencies, it is still important to understand the risks associated with each one.
How often should I review my crypto allocation?
There is no specific schedule for reviewing a portfolio. Some investors review their asset allocation at regular intervals, while others review it when their financial circumstances or investment goals change. What matters is whether your portfolio still reflects your intended level of risk and the role you want crypto to play within it.
Is cryptocurrency suitable for long-term investing?
Cryptocurrency can be held as a long-term investment, but a longer timeframe does not remove the risks associated with it. Crypto prices can remain volatile over extended periods, and there is no guarantee that an individual cryptocurrency will retain or increase its value. Anyone considering a long-term allocation should take these risks into account alongside their wider investment strategy.
