Features

• Transaction Fetching: Retrieve all transactions for a given Bitcoin address.
• Transaction Analysis: Calculate and display the net amount sent or received in each transaction, taking into account the amounts received as change.
• Price Logging: Log the Bitcoin price at the time of each transaction.
• Excel Export: Offer an option to download the transaction log and price data as an Excel file.

Dependencies

The program relies on several external Python libraries:

• requests: For making HTTP requests to fetch transaction data.
• datetime: For handling dates and times, specifically for formatting transaction timestamps.
• openpyxl: For reading from and writing to Excel files.

Additionally, it utilizes custom modules:

• prevout: To search previous outputs (prevouts) for a given transaction.
• mempool_requests: To fetch transaction data and Bitcoin prices.
• write_to_excel: To write transaction data to an Excel file and log prices.

Constants

• BTC_DECIMAL: A constant used to convert Satoshi to Bitcoin (1 BTC = 10^8 Satoshi).

Main Functionality

1. Input Bitcoin Address: The program starts by prompting the user to enter a Bitcoin address for analysis.
2. Fetch Transactions: It retrieves all transactions associated with the provided Bitcoin address.
3. Analyze Transactions: For each transaction, the program:
   • Identifies inputs (vin) and outputs (vout).
   • Checks if the transaction includes the given Bitcoin address either as a sender or a receiver.
   • Calculates the net amount sent or received in the transaction.
   • Fetches the Bitcoin price at the time of the transaction.
4. Display Transactions: Displays each transaction's details including date, block height, transaction ID, amounts sent or received, and the Bitcoin price at the transaction time.
5. Download Option: After displaying all transactions, the program asks the user if they wish to download the transactions as an Excel file.
   • If yes, it proceeds to save the transaction data and price logs into an Excel file.
   • If no, it exits without downloading transactions.
