I do not like that many fake copies exist and there is a great risk of giving away your private key. If possible, a two-factor solution can help.
It's also alarming that they are being targeted to be imitated by these scammers and phishers. I can't blame myetherwallet.com for being popular and one of the most preferred ETH and ERC 20 tokens wallet. They are literally safe if you know how to use it since they are very easy to use. The thing is that you need to be careful not to them but to the fake ones that are trying to copy them, just always look at the URL and you'll be fine.
