My MEW got hacked and my tokens were stolen. I am very careful when putting my address on each bounty campaign and never sign up online which require any private key. I don't really know how I get phish or how hacker accessed my MEW. I learned my lesson and will never use private key again. Do you have any idea how I get phish? I got one in mind that a fake mew site does exist?
There is nothing really new in what you are describing to us, you used your private key as a login to my ether wallet so the most likely option is that you entered your private key in a phishing site and then the hacker took advantage of it and stole your coins, be more careful next time, I know it is an expensive lesson to learn but people need to be more careful when storing our coins.
