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?
LOL, why should MEW not work anymore? Maybe the site is down sometimes and you can't create a new wallet or access your wallet you used before but it's only the site most likely has some problems and devs need time to repair it. If you want to create a wallet you can also do it offline. Just go to github, MEW, download it and you can start creating your new MEW.
