From various sources, MyEtherWallet (MEW) are not under development and maintenance any more. Even its founders has confirmed that they are switching to develop a new platform called mycrypto and encourage everybody to move there property to there.
But IMO, MEW or mycrypto is just a gateway to access your real wallet in the blockchain, so, both of them are still fine event MEW is not maintained anymore, right?
I don't know that where had you heard about the information that MEW are not under development and maintenance any more?? Everything is still Ok and their team are still working hard and I am also using the MEW to save and transfer tokens completely normal
