indeed some of the founders and developers of MEW made new wallet providers under the name MyCrypto and this happened a few months ago. don't worry, because both are safe and I still use both. if you are afraid, then you can use other wallets, such as metamask, electrum, coinomi, jaxx and hardware wallets.
I hope when they finish we'll get another good alternative. The most important thing is that it would be as safe as possible.
