+
+## Project Overview
+
+A Python tool that tracks Bitcoin and Ethereum addresses to identify the first cryptocurrency purchase - essential for Romanian crypto tax calculations. The tool analyzes blockchain transactions backward in time to find when crypto was first acquired from an exchange.
+
+## Architecture
+
+**Single-file application** ([crypto_tracker.py](crypto_tracker.py)) with one main class:
+
+- `CryptoTracker`: Core class handling both BTC and ETH tracking
+  - `track_bitcoin_address()`: Uses blockchain.info API (no API key required)
+  - `track_ethereum_address()`: Uses Etherscan API (optional API key)
+  - `_check_exchange()`: Matches addresses against known exchange wallets
+  - `_display_bitcoin_results()` / `_display_ethereum_results()`: Formatted output
+  - `main()`: Interactive CLI entry point
+
+**Data flow**: User address → API fetch → Parse transactions (oldest first) → Identify exchange sources → Display first purchase with date/amount/hash
+
+## Development Commands
+
+### Run interactive mode
+```bash
+python crypto_tracker.py
+```
+
+### Run tests (with public addresses)
+```bash
+python test_tracker.py
+```
+
+### Install dependencies
+```bash
+pip install -r requirements.txt
+# or simply:
+pip install requests
+```
+
+## Key Implementation Details
+
+**Bitcoin tracking**:
+- Uses blockchain.info free API (`https://blockchain.info/rawaddr/{address}`)
+- Hardcoded list of known exchange addresses in `known_exchanges` dict
+- Processes transactions in reverse chronological order to find oldest first
+- Converts satoshi to BTC (÷ 100,000,000)
+
+**Ethereum tracking**:
+- Uses Etherscan API (`https://api.etherscan.io/api`)
+- Free tier: 5 requests/second without API key
+- Converts wei to ETH (÷ 10^18)
+- Manual verification required for exchange detection (Etherscan address tags)
+
+**Exchange detection**:
+- Bitcoin: Direct address matching against `known_exchanges` dictionary
+- Ethereum: Flagged for manual review (addresses should be checked on Etherscan for exchange tags)
+
+## Extending the Codebase
+
+**Adding new exchanges**: Update `known_exchanges` dict in `__init__()` with exchange name as key and list of known wallet addresses as value.
+
+**Adding new blockchains**: Follow the pattern of `track_bitcoin_address()` / `track_ethereum_address()` - create new method, fetch transactions via blockchain API, parse chronologically, identify exchange markers.
+
+**Testing**: [test_tracker.py](test_tracker.py) uses public addresses (Genesis block for BTC, Ethereum Foundation for ETH) to verify API connectivity and parsing logic.
+
+## Important Constraints
+
+- **Read-only operation**: No private keys, no transactions sent
+- **Rate limits**: Ethereum API limited to 5 req/sec without key
+- **Exchange detection limitations**: Only major exchanges in Bitcoin; Ethereum requires manual verification
+- **Not for privacy coins**: Only supports transparent blockchain analysis

+# 🔍 Crypto Address Tracker - Găsește Prima Achiziție
+
+Program Python care urmărește automat adresele de Bitcoin și Ethereum pentru a găsi prima ta achiziție - esențial pentru calculul impozitului pe crypto în România.
+
+## 📋 Ce face programul?
+
+✅ Analizează orice adresă Bitcoin sau Ethereum  
+✅ Urmărește toate tranzacțiile înapoi în timp  
+✅ Identifică exchange-uri cunoscute (Binance, Coinbase, Kraken, etc.)  
+✅ Găsește **prima ta achiziție** cu data exactă  
+✅ Îți oferă link-uri pentru a verifica prețul istoric  
+
+## 🚀 Instalare
+
+### Pas 1: Instalează Python
+Dacă nu ai Python instalat:
+- Windows: Descarcă de la [python.org](https://www.python.org/downloads/)
+- Mac: `brew install python3`
+- Linux: `sudo apt install python3 python3-pip`
+
+### Pas 2: Instalează dependențele
+```bash
+pip install -r requirements.txt
+```
+
+SAU simplu:
+```bash
+pip install requests
+```
+
+## 💻 Cum se folosește
+
+### Mod 1: Interactiv (cel mai simplu)
+```bash
+python crypto_tracker.py
+```
+
+Apoi urmează instrucțiunile pe ecran:
+1. Alege Bitcoin sau Ethereum
+2. Introdu adresa ta de wallet
+3. (Pentru Ethereum) Optional: adaugă API key de la Etherscan
+
+### Mod 2: În cod (pentru programatori)
+
+#### Bitcoin
+```python
+from crypto_tracker import CryptoTracker
+
+tracker = CryptoTracker()
+results = tracker.track_bitcoin_address('1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa')
+
+if results['first_purchase']:
+    print(f"Prima achiziție: {results['first_purchase']['date']}")
+    print(f"Exchange: {results['exchange_found']}")
+```
+
+#### Ethereum
+```python
+tracker = CryptoTracker()
+results = tracker.track_ethereum_address('0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb')
+
+if results['first_purchase']:
+    print(f"Prima achiziție: {results['first_purchase']['date']}")
+```
+
+## 📱 Unde găsești adresa ta de wallet?
+
+### Bitcoin
+- **Blockchain.com wallet**: Settings → Addresses
+- **Ledger/Trezor**: În aplicația wallet-ului
+- **Exchange (Binance, etc)**: Wallet → Deposit → Bitcoin → Vezi adresa
+
+### Ethereum
+- **MetaMask**: Click pe numele contului pentru a copia adresa
+- **MyEtherWallet**: Se vede în dashboard
+- **Exchange**: Wallet → Deposit → Ethereum → Vezi adresa (începe cu 0x)
+
+## 🎯 Ce informații vei primi?
+
+Programul îți arată:
+- ✅ **Data primei achiziții** (FOARTE IMPORTANT pentru impozit!)
+- ✅ **Exchange-ul sursă** (Binance, Coinbase, etc.)
+- ✅ **Suma primită**
+- ✅ **Hash-ul tranzacției** (pentru verificare)
+- ✅ **Link direct către blockchain explorer**
+- ✅ **Link pentru preț istoric**
+
+## 📊 Exemplu de rezultat

+📊 REZULTATE:
+======================================================================
+
+🎯 PRIMA ACHIZIȚIE GĂSITĂ!
+   Exchange: BINANCE
+   Data: 2021-03-15 14:23:45
+   Sumă: 0.50000000 BTC
+   Hash: 3a4b5c6d7e8f9g0h1i2j3k4l5m6n7o8p9q0r1s2t3u4v5w6x7y8z9

+   🔗 Vezi tranzacția: https://blockchain.com/btc/tx/3a4b5c6d...
+
+   💰 Pentru preț istoric, verifică:
+      https://coinmarketcap.com/currencies/bitcoin/historical-data/
+      Data: 2021-03-15
+```
+
+## 💡 Următorii pași după ce găsești data
+
+1. **Notează data primei achiziții**
+2. **Mergi pe CoinMarketCap/CoinGecko** și caută prețul istoric pentru acea dată
+3. **Acesta este prețul tău de achiziție** pentru calculul impozitului
+4. **Calculează profitul**: Preț vânzare - Preț achiziție = Profit
+5. **Impozit = Profit × 10%**
+
+## 🔑 API Key pentru Ethereum (Optional)
+
+Pentru rezultate mai rapide la Ethereum, obține un API key gratuit:
+
+1. Mergi la [etherscan.io/apis](https://etherscan.io/apis)
+2. Creează cont gratuit
+3. Generează API key
+4. Folosește-l când programul te întreabă
+
+**Fără API key**: 5 requests/secundă (suficient pentru majoritatea cazurilor)  
+**Cu API key**: Rate limit mai mare
+
+## ⚠️ Limitări
+
+- **Bitcoin**: Identifică exchange-uri majore, dar nu toate
+- **Ethereum**: Trebuie verificat manual pe Etherscan dacă adresa are tag de exchange
+- **Privacy coins** (Monero): Nu pot fi urmărite
+- **Mixere/Tumblers**: Greu de urmărit
+- **Transfer între wallet-uri proprii**: Trebuie urmărit manual mai departe
+
+## 🛡️ Securitate
+
+✅ **100% Safe**: Programul folosește doar API-uri publice  
+✅ **Read-only**: Nu are acces la private keys  
+✅ **Nu trimite date**: Totul rulează local pe calculatorul tău  
+✅ **Open source**: Poți verifica codul  
+
+## 🐛 Probleme comune
+
+### "ModuleNotFoundError: No module named 'requests'"
+```bash
+pip install requests
+```
+
+### "No transactions found"
+- Verifică că adresa este corectă
+- Unele adrese noi pot să nu aibă istoric încă
+
+### "API rate limit exceeded" (Ethereum)
+- Așteaptă 1 minut și încearcă din nou
+- SAU obține un API key gratuit de la Etherscan
+
+### Nu găsește exchange-ul
+- Programul arată primele tranzacții
+- Verifică manual pe blockchain explorer dacă exchange-ul are tag
+
+## 📞 Suport
+
+Dacă întâmpini probleme:
+1. Verifică că ai Python 3.7+: `python --version`
+2. Verifică că ai instalat `requests`: `pip list | grep requests`
+3. Rulează cu debug: `python -v crypto_tracker.py`
+
+## 🎓 Pentru dezvoltatori
+
+### Extensii posibile
+- Adaugă suport pentru mai multe blockchain-uri (Solana, Cardano, etc.)
+- Integrare cu CoinMarketCap API pentru prețuri istorice automate
+- Export către Excel/CSV
+- GUI cu Tkinter sau web interface cu Flask
