Someone promises: 'Send bitcoin and you will get twice as much back.' What should you do?

Card answer

Correct answer

Answer C: Send nothing; it is a fraud warning sign.

Quick explanation

'Send bitcoin and you will get more back' is a classic scam. Logos, comments or even small initial repayments do not prove that later amounts will be safely returned.

Detailed explanation

In a doubling giveaway, the victim is told to send bitcoin to a specified address first, with a larger amount promised in return. After payment, there is no technical or contractually verifiable assurance that anything will come back. Irreversible payments make the pattern attractive to scammers.

The presentation can be highly convincing. Attackers take over social accounts, copy websites, reuse old video footage or generate voices and images with AI. A displayed transaction counter or supposed repayments can be entirely fabricated. Even a blue check offers only limited evidence of who controls the account at that moment.

Not every giveaway is automatically illegal, but a legitimate offer does not demand bitcoin first to send back more bitcoin. The protocol itself does not prohibit gifts or refunds; the fraud lies in the false promise. The right response is not to pay, to report the content and to verify the claim through an independent official channel.
