The flash BTC / USDT mechanism operates by creating temporary Bitcoin / USDT transactions that appear to be valid for a brief period. These transactions are generated using sophisticated techniques, allowing them to be recognized as legitimate by some blockchain / Tron networks for a short time. The primary goal is to provide a rapid, temporary balance in the recipient's wallet, which can be used to demonstrate funds or for other purposes. However, these transactions do not actually transfer real Bitcoins or USDT and will eventually be invalidated or rejected by the broader Bitcoin / Tron network, as they lack the necessary confirmations to become permanent. This method is often used for testing, demonstrations, or in some cases, malicious activities.
