This all happened on August 13, the day that Elon Musk was going to have the long meeting with President TRUMP. I was all excited to watch it, and when I got on youtube just before the meeting was supposed to start, I saw the supposedly fake video of Elon pushing his coin doubling thing, and that's where I pwned myself to the tune of 3.32 ETH, or $9000. I'm still amazed I didn't at least google it first, I know better than this.
So sorry about your loss, you lost a lot of money there. You fell for a crypto doubling scam and i am sure the scammers used deepfake Ai to impersonate Elon Musk and push their scam agenda, i am sure you'll be more careful next time.
When I got in touch with Coinbase reps about it, they were able to look up the transaction and that's where this talk of an external coinbase wallet comes from, that's what they said. I tried a couple times to talk to someone and get a better answer.
I can understand, it is difficult to get a favorable response from support. You have nothing to lose, so maybe you can still send them a few messages regarding it to see what happens.
