you need to prove with transaction id not with screenshot, screen shot can be photoshopped, what is the address to which you send the 10 btc? also have you contacted their support first before saying that they are scamming?
Your question does not make senses, how can he post a tx id? Tx id of what? Withdrawals? If he said that he have not received the withdrawal how can he post tx id? If you ask about deposit tx id, did he said that he win it from deposit money?
