I heard that the wallet MEW may not be used anymore, this information is true. So if the wallet MEW for some reason can not be used then can we use any other wallet?
Why do you believe in an unknown source? Do you have an official link?
MEW wallet can still work perfectly but the problem with it is that it's not really secured because hackers do hack their website and get away with people's token.
Well, I have never heard of the hacked Myetherwallet websites. Recently, Google DNS servers have been hacked, but this is not MEW fault, which is the fault of the Google server. (yeah, Do you know Google DNS?) Basically you will be directing to phishing websites when accessing to MEW sites. And if you are careful, you will easily recognize it as a phishing site.
