A scammer sends you a "flashed" payment for a real-world item. You see the Bitcoin in your wallet, release your goods, and then the Bitcoin disappears 24–48 hours later because it was never a real transaction. 🛡️ How to Stay Safe

If you need fast, legitimate Bitcoin transfers, use recognized Layer-2 solutions rather than unconfirmed "flash" tricks: The Lightning Network

: The transaction appears as "pending" or "unconfirmed" in a recipient's wallet, creating the visual impression that funds are on the way. The Mechanism : Scammers use techniques like Replace-by-Fee (RBF)

: These apps create "ghost" transactions that appear as pending in a recipient's wallet but never actually confirm on the blockchain . Scammers use these to trick victims into releasing real assets before the fake transaction disappears .

Scammers often charge "activation fees" or "gas fees" to download or use the software; once you pay, they disappear, and the software never works. How to Verify Real Transactions

: Be wary of transactions marked with RBF (Replace-by-Fee) , as they can be cancelled or altered before they are confirmed.
