Bitcoin for retirement? Opportunities, risks, limits

In retirement planning, Bitcoin can play a supporting role at most – and even that needs a plan for tax, withdrawals and inheritance.

Where Bitcoin stands in the retirement system

Retirement provision in Germany rests on three pillars: basic provision (the statutory pension, civil-service pensions, professional pension schemes), subsidised provision (such as Riester, occupational pensions and, in future, the Altersvorsorgedepot) and unsubsidised private provision.^[1]

Subsidised provision has no room for Bitcoin. The Altersvorsorgedepot, a state-subsidised retirement investment account that providers may offer from 1 January 2027, may only hold certain funds and bonds from public issuers. Crypto-assets and Bitcoin ETPs are excluded, as are individual shares and certificates.^[2],[3] So Bitcoin belongs, if anywhere, in the third pillar: private provision without state support.

Opportunities and risks as a building block for retirement

The horizon: time helps – until shortly before retirement

While you are saving, history argues for patience. Since 2013, a purchase on any given day was in profit three years later in around 99% of cases, measured in US dollars.^[4] That’s no guarantee: a purchase on 29 November 2013 was still around 35% down three years later, and one on 16 December 2017 around 13% down after five years.^[4]

After the big highs of 2013, 2017 and 2021, it took 28 to 39 months to reach a new high. From the high on 6 October 2025 (around $124,700), the price fell 53% by 30 June 2026.^[4] It currently stands at $86,292. Just over 13 years with a handful of cycles is thin statistics – more in Returns & risk.

In retirement planning, this advantage runs out: the closer you get to retirement, the less time is left to sit out a slump. A 70% fall at 30 still leaves you decades. The same fall at 66, when you want to live on the money from 67, is a real problem.

An allocation, not a foundation

If Bitcoin plays a role, it’s as a small building block alongside a broadly diversified foundation. Two studies show what ‘small’ can mean. Both come from asset managers that earn money from Bitcoin products themselves, and both look back.

• Bitwise (60% equities, 40% bonds, 2014–2025): with 2.5% Bitcoin and quarterly rebalancingGlossaryRebalancingBringing your asset allocation back to its planned shares. If the bitcoin share has risen sharply, you sell some; if it has fallen, you top up. This keeps your risk within the limits you set yourself.On the learning path: Stage 3 · Step 3 – Returns & risk →In the glossary →×, the return rose from 7.10% to 9.18% a year, and the largest interim loss from 22.1% to 23.7%. Without rebalancing, the Bitcoin share grew sharply in boom phases and the largest loss rose to around 51%.^[5]
• BlackRock (ten years to May 2026): 1–2% Bitcoin would have improved risk-adjusted returns. The position size should suit your goals and your capacity to bear risk.^[6]

Why the share matters more than the price: suppose your retirement savings amount to $100,000 (the ratio is the same in any currency). If 3% is in Bitcoin and the price falls by 80%, you lose $2,400 – 2.4% of your savings. With 30% in Bitcoin, it would be $24,000. This isn’t a recommendation for any particular share. More in Bitcoin as a small portfolio allocation.

Tax: the one-year rule and the risk of reform

Under current German law, gains on privately held bitcoin are tax-free if more than one year lies between purchase and sale (the holding periodGlossaryHolding period (speculation period)In Germany, the gain from selling privately held bitcoin is tax-free if more than one year passes between purchase and sale (§ 23 EStG, as of September 2026).

Over decades, that’s a big advantage – but not a certain one. A draft bill from the Federal Ministry of Finance (Referentenentwurf) proposes taxing gains on crypto-assets bought after 31 December 2026 at the 25% flat-rate withholding tax (Abgeltungsteuer) plus solidarity surcharge – 26.375% in total – regardless of how long they are held. Older holdings would keep the one-year rule.^[9] As of 24 September 2026, the cabinet had not approved the draft, and no government bill had been put before the Bundestag.^[10] The reform tracker follows the latest status and other proposals.

Directly or in a securities account?

There are no Bitcoin ETFs in the EU, because funds under the UCITS rules must be broadly diversified. Instead, exchange-traded products (ETPsGlossaryETP (Exchange Traded Product)Umbrella term for exchange-traded securities such as ETFs, ETCs and ETNs. With a Bitcoin ETP, you hold a security that tracks the price – but no bitcoin keys of your own.On the learning path: Stage 4 · Step 1 – Ways to get Bitcoin →In the glossary →×) are offered; according to justETF, their ongoing costs range from 0.05 to 2.00% a year (as of September 2026).^[11] Over 30 years, 2.00% a year eats up around 45% of the final value, 0.25% around 7% (simplified calculation). We don’t recommend individual products.

If you’re unsure what applies to a particular product, ask a tax adviser. The differences are explained in Bitcoin ETPs in your securities account.

Withdrawal: from saving to spending

Slumps at the start of the withdrawal phase can mean that too much wealth is used up early and the rest doesn’t last a lifetime. Experts call this sequence-of-returns risk.^[12] With Bitcoin it weighs especially heavily: since 2013, the price has fallen by 77 to 85% three times.^[4] Rules of thumb such as the 4% rule (withdraw 4% of your starting wealth each year, adjusted for inflation) come from long histories of equities and bonds and are disputed even there.^[12] For Bitcoin, the history is too short for a ‘safe withdrawal rate’.

Building blocks for planning – food for thought, not a recommendation:

1. Two pots: keep what you need for the next two to three years in low-volatility form, such as an instant-access savings account. Only top up from Bitcoin when the price is above a level you set in advance.
2. Withdrawal by rebalancing: only sell when the Bitcoin share is above its target. That way you tend to sell after rises rather than in a slump.
3. Keep tax in view: before each sale, check whether the one-year period has passed for the bitcoin you are selling.

Be careful with ‘don’t sell, borrow against it’: loans with bitcoin as collateral can be forcibly liquidated in a price crash. October 2025 showed how quickly that can happen, when leveraged positions were liquidated en masse.^[6] Practical steps are described in Selling & cashing out Bitcoin.

Inheritance: the plan that’s often missing

With securities in an account, the bank handles the estate. With self-custodied bitcoin, nobody can restore access: if your heirs don’t know about them or can’t get to the recovery data, the bitcoin are lost.

That’s why your plan needs an emergency letter that explains what exists and how to proceed – without the seed phraseGlossarySeed phrase (recovery phrase)A sequence of usually 12 or 24 words from which your wallet derives all its private keys. Anyone who knows the words has full access to your bitcoin – so they belong in an offline backup and never in anyone else’s hands.On the learning path: Stage 5 · Step 3 – Backing up your seed phrase →In the glossary →× itself. How to do this is shown in Inheritance & emergency plan. For German tax purposes, the holding period so far passes on with bitcoin you give away or leave to someone.^[7] Allowances and deadlines are explained in Gifting & inheriting Bitcoin.
