I remember watching the SpaceX channel on youtube, which isn't a legit source. AI Elon basically says "I want to help make bitcoin more popular, let me show you how easy it it to transfer money around with btc. Send my $X and I'll send you back $2X! It's very inline with a typical elon message (I'll give you 1 million to vote R), it's on a channel called SpaceX. It's pretty believable.
Granted I played Runescape and EvE as a kid, so any double-isk scams are immediate redflags.
Even Elon could lose his credit card or something, the story they spin is always something like that "I am rich but in a pickle, please send some money here and then I'll send you back 10x as much tomorrow when I get back to my account", but of course they never send it back.
Edit: But of course Elon would call someone he knows rather than a stranger, rich people know a lot of people so of course they would never contact you about this.
It doesn't make that much sense idk
