Crypto Reality Check
Cryptocurrencies are high-risk speculative assets, not necessary for wealth building. Most financial experts recommend 0% crypto allocation in portfolios. If you decide to invest: only after building an emergency fund and starting an ETF savings plan, maximum 0-4% of portfolio, only with money you can afford to lose completely [1].
Key facts: 10% of Germans own cryptocurrency [2]. Bitcoin has dropped 77-94% four times in its history [3]. Holding for more than one year exempts profits from tax in Germany [4].

The Honest Risk Assessment
Why Crypto Is Riskier Than ETFs
| Factor | World Index ETF | Bitcoin | Altcoins |
|---|---|---|---|
| Regulation | ✅ Strong | ⚠️ Growing | ❌ Minimal |
| Backing | ✅ Real companies | ⚠️ Network effect | ❌ Often nothing |
| Realistic max loss | -50% (market crash) | -80% (happened before) | -100% (common) |
| Historical recovery | ✅ Always recovered | ⚠️ So far yes | ❌ Often never |
| Recourse for fraud | ✅ BaFin (financial regulator) | ⚠️ Limited | ❌ Practically none |
Crypto Winters in History
| Period | Bitcoin from → to | Drawdown |
|---|---|---|
| 2011 | $32 → $2 | -94% |
| 2013-2015 | $1,200 → $200 | -83% |
| 2017-2018 | $20,000 → $3,200 | -84% |
| 2021-2022 | $69,000 → $16,000 | -77% |

Each time Bitcoin recovered. There is no guarantee this will repeat in the future.
Cryptocurrency Investment Rules
Rule 1: Only Money You Can Afford to Lose
Many financial experts, including analysts from Vanguard and traditional investment firms, recommend 0% cryptocurrency in long-term investment portfolios [1]. Cryptocurrency is not necessary for wealth building. Any crypto investments should be treated as high-risk speculation, not investment.
| Category | How Much |
|---|---|
| Emergency fund | ❌ Never |
| Retirement savings | ❌ Never |
| ETF savings plan money | ⚠️ Maximum 0-4% (many recommend 0%) |
| "Play money" (discretionary funds) | ✅ Acceptable |
Test: If your crypto drops to €0 tomorrow — would it change your life? If yes: you've invested too much.
Rule 2: Only What You Understand
| Before Buying | Understanding Criteria |
|---|---|
| Bitcoin | Can you explain the Proof of Work mechanism? |
| Ethereum | Do you understand the concept of Smart Contracts? |
| Altcoin XYZ | Have you read the project's technical whitepaper? |
| Any token | Can you explain why the token should have value? |
If you can't answer these questions, you should not invest.
Rule 3: Never on Credit, Never Borrowed
| ❌ Never | Why |
|---|---|
| Crypto on credit | Debt + loss = catastrophe |
| Borrowing money for crypto | Destroys personal relationships when losses occur |
| Overdraft (Dispo) for "buying the dip" | Most expensive type of debt (8-12% annual) + most volatile asset |
| Student money for crypto | BAföG (government student aid) or parents' money — not for speculative assets |
Rule 4: Secure Storage
| Option | Security | Effort |
|---|---|---|
| Exchange (Coinbase, Kraken) | ⚠️ Medium | Low |
| Hardware Wallet (Ledger, Trezor) | ✅ High | Medium |
| Paper Wallet | ✅ High | High |
Core security principle: "Not your keys, not your coins." If an exchange gets hacked or goes bankrupt (like FTX in 2022 [8]), cryptocurrency on its accounts may be lost.
Crypto Taxes in Germany
Core Rules
Cryptocurrencies in Germany are classified as private transactions (private Veräußerungsgeschäfte) and fall under § 23 EStG (Einkommensteuergesetz — income tax law) [4].
| Rule | Explanation |
|---|---|
| Holding period under 1 year | Profit is taxed at personal income tax rate |
| Holding period 1 year or more | Profit is completely tax-free |
| Exemption limit (Freigrenze) | €1,000 profit per year — profits below this are not taxed [4] |
Examples
| Scenario | Tax? |
|---|---|
| €500 profit after 8 months | ✅ Yes |
| €500 profit after 13 months | ❌ No |
| €2,000 profit after 8 months | ✅ Yes, on everything |
| €900 profit after 8 months | ❌ No (under €1,000) |
Documentation for Tax Authorities
The tax office (Finanzamt) requires documentation:
- Purchase date and price of each cryptocurrency
- Sale date and price
- Which specific coins are being sold (FIFO principle — First In, First Out applies)
Tracking tools: CoinTracking, Blockpit, Accointing, or manual tracking in Excel [4].
Serious Crypto Strategy (If Any)
The "Satellite" Approach
| Core Portfolio | Satellite (Crypto) |
|---|---|
| ETF savings plan | 96-100% |
| Bitcoin only | 0-4% maximum |
Conservative position: Many financial experts recommend 0% crypto in portfolios [1]. Conservative allocation for those interested in cryptocurrency — maximum 1-2%. More than 4% moves into speculation category.
Why specifically Bitcoin? It's the oldest (since 2009) and largest cryptocurrency by market capitalization with the longest history of recovery after crashes [3]. If investing in crypto — choose the most time-tested asset.
DCA Instead of Trying to Catch the Bottom
| Strategy | Description | Risk |
|---|---|---|
| Lump sum at "the bottom" | All capital at once | High (impossible to predict bottom) |
| DCA (Dollar Cost Averaging) | Same amount every month | Lower (averages entry price) |
DCA (dollar cost averaging) is an automatic purchase plan (Sparplan) of a fixed amount at regular intervals. Same principle used for ETF investing.
Red Flags: Signs of Fraud
| Warning Signal | What It Means |
|---|---|
| "Guaranteed 100x returns" | Fraud — nobody can guarantee returns |
| Telegram groups with "trading signals" | Pump & Dump schemes [6] |
| Influencer promotional posts | Paid advertising without disclosure of conflict of interest |
| "The next Bitcoin" | Over 20,000 projects claim this; most fail [5] |
| FOMO (fear of missing out) | Emotional buying at price peaks |
| "Trust me, explaining would take too long" | If you can't understand the project — don't invest |
Common Mistakes
| ❌ Mistake | ✅ Better |
|---|---|
| All-in on one altcoin | If crypto at all, then Bitcoin |
| Buying because everyone's buying | Buying because you understand |
| Panic selling at -30% | Aim for 1-year holding period |
| "Forgetting" about taxes | Document from day 1 |
| Leaving keys on exchange | Use hardware wallet |
| More than 4% of portfolio | Max 0-4%, many say 0% |
The Honest Summary
| For Whom Crypto Might Be Okay | For Whom Not |
|---|---|
| ✅ Emergency fund already built | ❌ No emergency fund |
| ✅ ETF savings plan running | ❌ No other investments |
| ✅ Has "play money" left over | ❌ Needs this money |
| ✅ Understands the technology | ❌ "Heard it goes up" |
| ✅ Can handle 100% loss | ❌ Would change lifestyle |

FAQ
How to assess whether to buy Bitcoin? Many financial experts believe 0% cryptocurrency in portfolios is the right allocation [1]. Criteria for considering investment: emergency fund exists, ETF savings plan running, understanding of technology, willingness to accept complete loss of invested funds. If all conditions met — maximum 0-4% of portfolio.
How to assess altcoins? Over 90% of altcoins fail [5]. For informed assessment requires minimum 10 hours per week researching projects, reading technical whitepapers, analyzing development teams. Even with deep research, risk of complete capital loss remains high.
How to interpret success of acquaintances in crypto investing? Survivorship bias — you hear success stories, but not about the majority who suffered losses. Important question: has profit been realized (sold with withdrawal to euros) or is it unrealized "paper" profit?
How to assess NFT investments? The NFT market fell over 95% from its 2021-2022 peak [7]. NFTs are appropriate to buy as digital art for personal interest, not as financial investment.
Cryptocurrency can be part of a portfolio — but only after building the foundation. Emergency fund, ETF savings plan, understanding of technology. Then, with money you're ready to lose completely. Not before.
