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?
I don't think that's true, myetherwallet can still be used. I have multiple tokens in myetherwallet so if that wallet cannot be used anymore then all of my tokens will be nonsense. I don't think that is true, the last time I check MEW is still working. Do you have any link that MEW may not be used anymore?
