I use it in order to store the tokens that I hold for long term. In my experience it is secure if you will use it properly and wisely. There are information phishing links everywhere, and you need to have caution and ensure safety every time you will log in to your myetherwallet.
I agree with you . There are many fake myetherwallet sites and many investors have accidentally entered their Privaty Key. I think we should be more careful because every transaction in this market is extremely dangerous and only one mistake you can lose everything.
