I made a mistake and invested $1000 in bitcoin on the bitcoin app not the bitcoin pro exchange. My plan was to invest a small amount and see that build up but I change my mind and would like to the whole value of a bitcoin which around $7300 right now not just $1000 worth. So how can I do this through the exchange? So now I need to invest around $6300.
I will advice that you might invest little amount of first, dont spend to much in only one trade. Or you may try to split your money, if you are going to have a $7300 then maybe you should put $3300 to other alt coins and the bigger amount would be sent to bitcoin investment. Just invest to those trusted exchange! Nothing else for you not to commit mistake again.
