I don't have any problem encountered on using MEW as of now, so i may still stick to this wallet. I know there are lots of issues and reports about MEW but on my opinion every wallet lost and stolen cryotocurrency are only happens when you carelessly use your private keys.
Yes there are many reports about hacking incidents but it doesn't belong to MEW's management.
It's a mismanagement coming from the users not from MEW itself.
As a user, we need to be careful as well and bookmark it so we can't be fooled by fake sites.
