I have same experience but I’m the one who’s selling my Bitcoin that time to my friend. He didn’t trust me that I’m selling him right price so he decided to purchased his own Bitcoin which he ended up being scam after using scam exchange that selling too good to be true Bitcoin price.
I confessed my story, because generally i dont tell people like this, and hardly people know how i bought my first bitcoin, though after so many years most people now thinks that i know much but yes i did make a mistake of knowing and buying bitcoin, thinking the transactions can only be successful through an exchange not on personal level...
