Someone offered to double my coins if I send some first. Is that real?

No, it is always a scam, with no exceptions. The "send coins, get more back" trick is one of the oldest and most common frauds in crypto. It often appears as a fake giveaway from a celebrity, a project, or even an account pretending to be the Malairte team. The promise feels exciting, which is exactly the point — excitement makes people act before they think. No legitimate person or project will ever ask you to send coins first in order to receive more. Once you send crypto, it cannot be reversed, so the coins are simply gone. If you see this offer anywhere, ignore it, do not reply, and consider reporting it. When something sounds too good to be true in crypto, it almost always is.
