Multi-Asset Allocation and Taxes in Germany: Tracking Stocks, ETFs, and Crypto Privately

There's a very specific kind of person in Germany who can tell you their exact savings rate, the TER of their MSCI World ETF, and the precise month they'll hit financial independence if markets return their historical average.

They've read the Frugalisten blog. They run their own spreadsheets. They DCA into a global index fund with the discipline of someone training for a marathon, except the marathon never ends and the finish line is a net worth that lets them quit on their own terms.

Across the border in Switzerland, there's another kind of investor who opened a crypto position through their Kantonalbank, holds Bitcoin in a hardware wallet, and is watching UBS roll out direct BTC and ETH trading with the quiet satisfaction of someone who was early to something that the entire banking establishment is now scrambling to catch up with.

And then there's the person who is both. The one with an ETF Sparplan at Scalable Capital, a Bitcoin position they've held for over a year (tax-free, thank you very much), and an apartment in Zürich or München that represents the largest single line item in their net worth.

That person has a portfolio allocation problem.

The DACH multi-asset portfolio is real

In the German-speaking world, the old divide between "traditional investor" and "crypto investor" is dissolving. People aren't choosing one or the other. They're choosing both.

Germany's ETF market has exploded. The number of ETF savings plans grew from 200,000 in 2014 to 9.5 million by the end of 2024, a 34% jump in a single year. Nearly 90% of all new retail fund money in Germany between 2023 and 2025 went into ETFs. Low-cost, self-directed, globally diversified index investing. The Frugalist playbook won.

At the same time, crypto adoption in the DACH region is accelerating from a different direction.

Switzerland now leads Europe with approximately 20 banks offering crypto services, more than any other country. Zürcher Kantonalbank launched crypto custody and trading in 2024, giving over 2.5 million Swiss accounts direct access. UBS followed in January 2026 with Bitcoin and Ethereum trading for private banking clients.

Swiss crypto companies raised $728 million in 2025 alone, up 37% from the previous year. This is no longer Crypto Valley's niche experiment. It's mainstream Swiss banking.

Germany has its own crypto story. Around 25 million Germans are expected to hold cryptocurrency. The Sparkassen network, with 50 million clients, announced plans to offer Bitcoin trading directly.

And then there's real estate. Property remains the anchor of wealth in the DACH region, whether it's a Wohnung in Berlin, a Reihenhaus in Stuttgart, or an apartment in Basel. For many investors, it's the single largest asset they own, and it sits in a completely different universe from their ETFs and crypto.

The result: a generation of DACH investors holding a genuinely diversified, multi-asset portfolio.

Three asset classes, three apps, three copies of your net worth

Here's how the tracking typically works.

The ETFs live at your broker. Scalable Capital, Trade Republic, Swissquote, or one of the traditional banks. That app shows your cost basis, your performance, maybe your dividend income. It requires an account, stores your data on their servers, and runs analytics to understand your behavior.

The crypto lives somewhere else. Maybe a hardware wallet. Maybe Kraken or Coinbase. Maybe directly through your bank now that Swiss and German banks are racing to offer it. Whatever app you use to see those balances wants your email, your exchange API keys, or both. Some of them, like getquin, want you to share your holdings publicly for social engagement.

The real estate lives nowhere. It's a number in a spreadsheet. Or a number in your head.

The privacy cost of seeing your own net worth

There's an irony in the DACH approach to investing. People in this region are, rightly, meticulous about privacy. Germany's Federal Constitutional Court recognized informational self-determination as a fundamental right in 1983.

The GDPR was built on European values of data minimalism and consent. Switzerland's Federal Act on Data Protection is among the strongest in the world.

Yet when it comes to financial data, the same people who refuse cookie banners hand over their complete portfolio to apps that store it on external servers, embed analytics SDKs, and share data with third-party services they've never heard of.

Financial data is not like other data. Your holdings reveal your wealth bracket, your risk tolerance, your political convictions (look at what you don't invest in), and your life trajectory. Your crypto wallet addresses, even on public blockchains, can be clustered and cross-referenced through chain analysis tools.

When AI systems aggregate this data, they don't just store it. They predict your behavior. They build a profile that makes you more predictable, more valuable to whoever's buying.

For German crypto investors in particular, the stakes are concrete. Germany's tax framework requires precise records of holding periods and transaction dates. Any platform storing your wallet addresses, transaction timestamps, and holding periods has a detailed map of your tax position.

A privacy policy doesn't fix this. A privacy architecture does.

What the Frugalist ethos actually demands

The Frugalist movement is built on a few core principles: spend less than you earn, invest the difference in low-cost, broadly diversified funds, and let compound growth do the work over decades. It's the anti-speculation philosophy.

But there's a principle underneath all of that which rarely gets discussed explicitly: control. The entire point of financial independence is owning your time and your choices. Not depending on an employer, a bank, or an institution to sustain your life.

If you believe in financial self-sovereignty, it's worth asking: does your portfolio tracker align with that belief?

When your net worth data sits on someone else's server, you don't control it. When an app requires your email to show you your own money, you've accepted a dependency that the Frugalist in you should find uncomfortable.

What private multi-asset tracking actually looks like

DecentWealth is a private portfolio tracker for iPhone, iPad, and Apple Watch that was designed for exactly this kind of portfolio. ETFs, stocks, crypto across 16 blockchains, real estate, retirement accounts, vehicles, cash, and loans. All in one app.

Here's how it works for a typical DACH multi-asset portfolio:

• Your MSCI World ETF. Search for it by name or ISIN. Log your transactions with purchase date and cost basis. See your performance, your allocation, and your unrealized gains. Over 100,000 stocks and ETFs are supported with real-time pricing, including listings on Xetra, Frankfurt, Vienna, and SIX Swiss Exchange.
• Your Bitcoin and Ethereum. Paste your wallet address. DecentWealth reads public blockchain data and shows your balance. No exchange API keys. No account connections. Your address is never stored on DecentWealth's infrastructure. Balances update automatically across Bitcoin, Ethereum, Solana, Polygon, Base, Arbitrum, Optimism, Avalanche, BNB Chain, and others.
• Your apartment in Zürich or Berlin. Add it as a real estate asset with your purchase price and current estimated value. Update it when you want. It sits alongside your stocks and crypto in your total net worth calculation. No third-party property API needed.
• Your total asset allocation. See everything together. What percentage is in equities, what's in crypto, what's in property. One number. One screen. On your device.

And here's what makes it different from every aggregator that promises the same thing:

• No account. You download the app. You start tracking. No email, no password, no personal information. There is no user database because we chose not to build one.
• On-device storage. Your portfolio data stays on your iPhone. It is never transmitted to any server. There are no DecentWealth servers holding user data.
• No in-app tracking. The app contains no analytics SDKs, no tracking pixels, no behavioral data collection. We don't know what you hold, how much you're worth, or whether you check your portfolio six times a day during a dip.
• End-to-end encrypted sync. If you use DecentWealth on both your iPhone and iPad, your data syncs through Apple's iCloud with end-to-end encryption. We never see it.
• 45 fiat currencies. View your portfolio in EUR, CHF, USD, or any of 42 others.
• CSV and PDF export. Export your transaction history by custom date range for tax reporting. Particularly relevant for German investors tracking crypto holding periods under the current tax rules.

Your allocation is your strategy. It should stay yours.

The classic 60/40 portfolio is dead. Everyone knows that. What replaced it is something more personal and more complex: a multi-asset allocation that reflects your actual life, your actual risk tolerance, and your actual beliefs about where the world is going.

Whatever your allocation looks like, it tells a story. About your plans. About your timeline to independence.

That story should exist in exactly one place: your device. Not on a company's server. Not in a database that could be breached, subpoenaed, or sold.

You've spent years building your portfolio with discipline and intention. Track it the same way.

Download DecentWealth free on the App Store, the app is available in German.
