Even I really feel sad for your loss but there is nothing can be done if someone loose Bitcoin for a scam exchange and that is the truth even it is bitter but the only way to gain you lost Bitcoin is to start from the beginning but nothing else and because now you have learned a good lesson through personal experience now is the time to make it to an advantage and at last what I have to say is you are not the first and you are not the last so you are not alone in this matter
