A Bitcoin-only portfolio tracker built for German Steuerpflichtige — automatic import from every major Bitcoin-Anbieter, gains calculated nach FIFO with the 1-year Haltefrist, and a one-click export to a Finanzamt-ready PDF that your Steuerberater actually accepts.
German retail Bitcoin holders who dread annual crypto tax filing
- Auto-import from Bitcoin.de, Kraken, Coinbase, and all major hardware wallets with German-language UI
- Haltefrist-Rechner that tags every sale as steuerfrei (>1 year) or steuerpflichtig and sums the realized gains in EUR
- Finanzamt-PDF export matching the Anlage SO and the BMF guidance for crypto assets
- Loss-harvesting planner that flags taxable lots you could offset against gains before year-end
Blocktrainer's analysis that 90%+ of altcoins are functionally dead pushes German crypto investors toward a Bitcoin-only strategy, but the German tax regime's interaction with crypto — especially the FIFO rule and 1-year holding period — still deters many would-be investors from properly tracking their books.
Multiple dedicated German-market comparison articles and 4+ active vendors (Divly, Blockpit, CoinTracking, Koinly) all specifically targeting DE — Divly reports ~2,600 paying users in early 2026, confirming real willingness to pay.Bester Krypto-Steuerrechner Deutschland 2026 ↗Krypto Steuer Tool Vergleich 2026 ↗
Saturated market: Blockpit (DE-founded, 160+ exchanges/190+ blockchains, 2,500+ dApps), CoinTracking (25+ report types, DE-localized), Divly and Koinly all already offer FIFO, Haltefrist, Anlage SO, WISO CSV — the 'Bitcoin-only' carve-out is too narrow to differentiate meaningfully.Blockpit: Smarte Krypto-Steuern & Portfolio-Tracking ↗CoinTracking: Der Krypto-Steuerrechner & Portfolio-Tracker ↗
Proven €39-€49/year pricing tiers across competitors (Divly €39/100 tx, Blockpit €49/50 tx, CoinTracking €39/200 tx, Koinly $49/100 tx) with recurring annual seasonality tied to German Steuererklärung deadline — clear willingness to pay for pain relief.Divly pricing (DE guide) ↗Blockpit Preise ↗
German §23 EStG FIFO + 1-year Haltefrist rules have been stable but require ongoing monitoring (MiCA implementation, 2026 EU DAC8 reporting rollout, possible Freigrenze changes); Blocktrainer 'altcoins dead' thesis is opinion-driven, not structural — long-term stable but with regulatory update overhead.Krypto-Steuern Deutschland 2025: Der komplette Guide ↗Krypto-Steuer-Rechner 2025 & 2026 ↗
Bitcoin-only simplifies chain support (no EVM/Solana/NFT/DeFi complexity), and FIFO + Haltefrist math is well-understood; but still requires maintaining API integrations with each 'Bitcoin-Anbieter' (Bitcoin.de, Kraken, Trade Republic, Coinbase, etc.) plus PDF generation acceptable to Steuerberater — moderate build, ongoing maintenance burden.Blockpit integrations overview ↗
