Please copy\paste web site adress of etherwallet that you are using for this, maybe you use some scam sites looks like myerther.
That would be my belief as well. To OP... did you use a bookmark to get to MEW? Did you manually type it in... or did you click a link in an email or on a website? I've seen a few posts about losing coin from a MEW wallet but I've yet to hear it official that it was '
hacked'.
**as a side note, if you clicked a link from a website, it'd be beneficial to post that here so others can be warned.**
Most of the hacker they used other site that has similar to mew, like Slack they most often sent you a flood site to your email and has an instruction to click this, if you see that kind of instruction in your email avoid then delete it at once. That's why for me slack for me is not safe to use it in the ico project telegram is much more better and good to use it for now.
