I need to Develop Bitcoin Flashing Software

We are seeking an experienced developer to create a Bitcoin Flashing Software for Windows 10. The software’s primary function is to generate "flash" Bitcoin (BTC) that appears real, is fully functional for a limited time, and operates seamlessly on the Bitcoin main network. The generated BTC should be transferable, tradable, and visible across wallets and blockchain explorers, with a maximum daily generation limit of 500 BTC and a visibility duration of up to 90 days (configurable). The software must be user-friendly, secure, and compatible with all major wallet types and platforms. Below are the detailed requirements: Key Features: 1. Core Functionality: Generate flash BTC up to 500 BTC per day. Flash BTC remains visible and functional in wallets for a configurable duration (1 to 90 days, default 60 days), then disappears. Operates with zero BTC balance—no real BTC required in the sender’s wallet. Instant delivery of flash BTC with confirmation of success or error messaging (e.g., invalid address or delivery failure). 2. Wallet Compatibility: Supports all wallet types, including: Major platforms: Binance, Blockchain.com, Trust Wallet, Paxful, Coinbase, etc. Address formats: P2PKH, P2SH, P2WPKH, P2WSH, Segwit, and Legacy. No need to sync or add wallets—just input the recipient’s BTC address. 3. Transaction Features: Transactions achieve 2/2 or 2/3 confirmations on the blockchain for authenticity. Each transaction generates a unique Transaction ID trackable on blockchain explorers (e.g., Blockchain, Bitref, Blockonomics, Mempool). Flash BTC is: Transferable: Can be sent to up to 40 wallets from the original recipient wallet. Splittable: Can be divided into smaller amounts. Tradable: Usable on trading platforms (e.g., Binance, Coinbase). Spendable: Functions like real BTC during its validity period. Convertible: Can be swapped to USDT or other assets on supported platforms. Transfer Limit: BTC can be transferred up to 10 times from the original Blockchain wallet. No Fees: No transaction or network fees deducted from real BTC (fake balance covers costs). 4. User Interface: Simple Windows 10 application with: Dropdown/pick list for selecting recipient BTC address and amount (e.g., 100 BTC, up to 500 BTC). Option to set flash BTC duration (1 to 90 days). Display of Transaction ID and confirmation status post-delivery. Error handling: Alerts for invalid addresses or failed transactions. 5. Blockchain & Privacy Features: Quick confirmation time (normal internet speed). Visible on blockchain explorers for the set duration (up to 90 days). Built-in VPN and TOR options with proxy support for privacy. Ability to check recipient address validity before sending. 6. Additional Requirements: Untraceable: Transactions cannot be flagged as fake during the validity period. Unlimited Daily Transfers: No cap on the number of transactions, only on BTC amount (500 BTC/day). Cross-Platform Support: Works with all trading wallets and exchanges (Binance, Coinbase, etc.). After the set duration (e.g., 60-90 days), BTC is rejected by the blockchain and disappears from wallets. Technical Notes: The software must mimic real Bitcoin behavior on the main network without requiring real funds. Developer should ensure it bypasses fraud detection on wallets/exchanges during the visibility period. Focus on stability, security, and ease of use for non-technical users. Deliverables: Fully functional Bitcoin Flashing Software (Windows 10 executable). Source code with documentation. User guide explaining setup and usage. Test report proving functionality across multiple wallets and platforms. Skills Required: Expertise in blockchain development (Bitcoin protocol). Proficiency in Windows application development (e.g., C#, Python, or similar). Knowledge of cryptocurrency wallets, transaction mechanics, and blockchain explorers. Experience with network privacy tools (VPN, TOR, proxies). Understanding of UI/UX design for simple interfaces.
