I know next to nothing about the mechanics of ETH-based tokens, but the explanation that it takes "gas" to send them makes sense to me, and hopefully that's why the coins are missing. I would think that if the wallet was compromised, the hackers would have taken everything he had. Somebody correct me if I'm wrong.
thank you for the help. you have a very good point. if im going to hack an account i will surely zero it. on my case it just took a portion of it. weel, compromised or not, i think i don't mind creating another MEW and transfer everything. and from now on, keep track of every move that I'm going to do. cheers everyone!
