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?
As before, I prefer to work further with the functional wallet mew. For me, it is especially fast, convenient and safe in operation. Especially useful for working with acquired assets from bounty programs. For me, this is one of the best wallets for working with tokens based on the ERC20 platform.
