I don't know what happened I just know that I tried to send it to my external wallet address but it went to an address that was SUPPOSEDLY my free bitco address BUT IT WASENT MY ADDRESS  I don't understand it at all and I know how to send Bitcoin im dead sure there was no mistake on my or any of the other contest winners that day . It happens to several people that day all the same way as I have described I'm telling you the truth it was not my fault whatsoever ever
