Just want to share my experience for a week ago.my wallet was hacked by a poor hacker in my opinion because in my wallet not more than $200 and the hacker was hacked only $80 when eth for the gas transaction was run out.very so sad when we waiting for the best price and i will sell it but it was hacked
maybe the hacker just used your eth balance to send token and because you don't have enough eth the other coins are not send out. and the hacker did not want to send eth to your account to send out the other tokens that is left. so the hacker did not lose anything but instead you are the one that lose some coins. this hacker maybe poor or maybe not but he/she is smart enough to hack you. so be careful next time to avoid being hack.
