Yes, I very much support the answers provided already. Supposedly, the wallet should be safe but like anything else hackers evolve and so does technology so one can never exclude the possibility of being hacked though at this time it would be expensive and would require lot of effort.
i heard that myetherwallet is fine but i have never used it myself so i do not have enough knowledge to share with you
Myetherwallet is really a nice wallet to use, though some people get hacked whn trying to access the website. The reason is because they are accessing a phishing website which is not mywtherwallet.com. So in order to be sure of your security please check your URL. Secondly if you don't want to be accessing the website, you can import your private key into another ERC-20 Compatible wallet such as Eidoo and imtoken. Hope this would help
