Meaning if you purchased Bitcoin or altcoins from some users in this community or other exchanges market without your knowledge that the person has use the same address to purchase Bitcoin or altcoins from another person meaning the person is the one controlling those accounts right? When I was financial strong as a beginners I purchased Bitcoin from people even till now am still purchasing Bitcoin when I have the fund. I have not experienced ban vision from this community, because I don't know why you included Sebas.tian in ban vision. Please Sebas.tian is an innocent for this accusations if truly you can go deep to investigate this matter very well.
