Sharing my free BTC whale tracker + Telegram alert bot (open to feedback)

[jzcjimmy]

Hey Bitcointalk,

I built a free Bitcoin whale tracker and Telegram alert bot —
no signup, no fees, just instant notifications when large BTC
transfers happen on-chain.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🐋 WHAT IT DOES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

- Monitors Bitcoin mempool in real time for transfers above 50 BTC
- Automatically identifies whether whales are sending BTC to
  exchanges (bearish) or self-custody (bullish)
- Sends instant Telegram alerts when large transfers are detected
- Classifies transfers by tier: Mega Whale (≥500 BTC),
  Whale (≥100 BTC), Large (≥50 BTC)
- Filters out change outputs and internal exchange transfers
  to reduce false signals

📊 SIGNAL TYPES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🔴 Exchange Deposit — Whale sending BTC to Binance, OKX,
   Coinbase etc. Potential sell pressure incoming.

🟢 Wallet Split — Whale moving BTC to self-custody.
   Accumulation signal, historically bullish.

🟠 Consolidation — Whale merging UTXOs before exchange deposit.
   Early warning signal, watch for follow-up exchange inflow.

⚙️ ALERT THRESHOLDS

Choose your own threshold:
- 50+ BTC (recommended for most traders)
- 100+ BTC (reduce noise, focus on larger moves)

  hot wallet database (Binance, OKX, Coinbase, Kraken, Bybit,
  Huobi, Bitfinex, Gate.io, Gemini)
