Everything you need to know about Bitcoin-Tech
Welcome to the Bitcoin-Tech Support Page
Bitcoin-Tech lets you manage your entire crypto portfolio — including physical coins and precious metals — privately and entirely on your device. No wallet keys.
Portfolio
Track your holdings, P&L and cost basis
Adding Holdings Manually
- Go to Portfolio in the sidebar
- Click Add Holding
- Search and select a coin from the dropdown
- Enter your amount and optional purchase price
- Save — the holding appears instantly in your portfolio
CSV Import (Binance / Coinbase)
Import your transaction history in one click. Supported format:

Understanding P&L
Unrealised P&L — current market value minus your total cost basis.
Cost basis is the purchase price you entered when adding / importing a holding.
If you leave the purchase price blank, the cost basis defaults to $0 — P&L will then equal the full market value.
Supported Asset Types

Tax Report
FIFO-based DE/EU tax calculations
How FIFO works
First-In, First-Out means when you sell coins, the oldest purchase is considered sold first. This is the method required by German tax law (§ 23 EStG).
DE / EU tax rules applied
- ✓ 1-year holding rule — coins held > 365 days are tax-free when sold (Germany)
- ✓ €600 exemption — annual private sale gains below €600 are exempt
- ✓ Filter by year — select any tax year to see only the relevant transactions
- ↓ Export — download as PDF or CSV for your tax advisor / Finanzamt submission
Physical Bitcoin Coins
Casascius, Denarium, Satori and more
What are physical coins?
Physical Bitcoin coins are collectible metal coins that embed a real Bitcoin private key under a tamper-evident hologram. Each coin has a fixed denomination (e.g. 0.001 BTC, 0.1 BTC, 1 BTC) stamped at minting time. Their fiat value moves with the Bitcoin price.
How values are calculated
Value = denomination_btc × BTC price × coin count
Example — 1 × 0.001 BTC coin at BTC = $100,000:
0.001 × $100,000 = $100.00
Supported manufacturers
Coin data (series, denomination, images) is sourced from the built-in database. Serial numbers are optional but help identify specific items.
Precious Metals
Gold, Silver, Platinum & Palladium
Amount unit
Metal amounts are always entered and stored in grams (g). Prices from the metals API are given per troy ounce (31.1034768 g) and automatically converted to per-gram internally.
Value formula
Value = grams × (price_per_oz ÷ 31.1034768)
Example — 2.5 g gold at $5,109/oz:
2.5 × ($5,109 ÷ 31.10) = $410.65
Frequently Asked Questions
No. CryptoTrack is a manual tracking tool. You enter your holdings yourself — no wallet connections, no API keys, no seed phrases are ever requested.
The prices are updated 3 times per day and cached locally. You can trigger a manual refresh from the settings or by clicking the refresh button on the Dashboard.
Currently one portfolio per user account is supported. Holdings from different exchanges (e.g. Binance and Coinbase) are distinguished by a "source" tag so you can filter them.
On the Portfolio page, click the three-dot menu next to any holding and select Delete. You can also enter a sell transaction via the Transactions tab, which will adjust the holding amount via FIFO.
No. The calculations follow German FIFO rules as a best-effort estimate. Always have a qualified tax advisor review your figures before submission.
Yes — all core features (portfolio view, P&L, tax calculations) work fully offline once the price data has been cached. Only the initial price fetch requires internet access.
Always grams. Enter your gold or silver weight in metric grams. The app internally divides the API price (per troy oz) by 31.1034768 to get the per-gram rate, then multiplies by your gram amount.
