Could someone explain to me why the transaction from Bittrex can't be seen on Etherscan Xaurum Token Tracker? Example: There was a transaction on Bittrex at 11:12:50 when somebody bought 40985.37 Xaurums. That transaction can't be find on Etherscan Xaurum Token Tracker. Why is that so?
When one buys or sells on an exchange, no (blockchain) transaction is actually performed, these are just numbers ... As nmrcngrb pointed out, withdraw and deposit operations are the one who generate transactions that are visible on explorers.
