5K bonus? Am I in trouble or what ?

Three weird things happen to me on Coinbase wallet.Today I cashed out of a phony crypto app, all of a sudden at the same time I get another transaction that I don’t remember buying but didn’t realized until I got home. a few hours later, I finally i get home and(felt good to be home) hop on my Mac and sign try signing on to my wallet. I couldn’t sign on(I guess Im getting old) so I decided to change my password on the chrome extension. I changed the password, everything is all good. Then a few hours later I sign on to the coin base wallet on my phone and see that other transaction. And I think I have an alert to changelog out or something like that. I also realized my money starts with “a$”. Which it never was like this. Was it because my Vpn was set to Australia?(maybe) I turned off my VON and it still says it the A$. Also when I changed my password and signed back on, my 2nd backup wallet wasn’t there. What’s going on!? And I almost forgot to mention, the transaction says 5000$ bonus on it.
