It's really simple. Use MyCrypto instead of Myetherwallet. It's made by the same team, It looks the same and it has more improvements so there is no reason why you wouldn't use it.
Its not made by the same team. Actually its more than that, there was some power grabbing MEW that resulted to some of them separating and putting up MyCrypto.
I haven't seen a single phishing attempt yet targeting Mycrypto, most likely because hackers are not really aware of it as of now as not many people use it. Either way, the domain name is shorter so It's unlikely that you'll fall it.
Yes. Because majority of investors are still using MEW because they're used to it. You just have to learn how to protect your account and you're good to go. Please there's a lot of helpful tips around that will reduce your chance of being phished.
