Fake MyEtherWallet deleted from the AppStore

3000 users were able to download fake MyEtherWallet app
13 December

On 10th of December, a Twitter user reported about the spotted suspicious application of popular Ethereum wallet at Apple AppStore.

And it became known that the app is fake. It is worth noting that the app isn't free. The iOS app costs $4.99 and it first landed on the App Store just over a week ago. It allows users to create or import a wallet to store cryptocurrencies independently of an exchange.

Finally, the fake app was deleted. We wasn't able to find the official comments from Apple, but MyEtherWallet team is happy.

This is not the first and maybe not the last fake scammy-looking thing in cryptocurrency world. We can only recommend you to extremely careful everytime you deal with money.
