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 have never heard of such news. I think they still maintain it to make a profit from the deal. There are a lot of ETH based ICO projects and the MEW wallet is an optimum solution for investors holding their altcoins. It's still a good wallet and I have no doubt about it.
