Control Over Your Money

The MyEtherWallet.com wallet relies on a centralized service by default. This means a third party must be trusted to not hide or simulate payments.
The MyEtherWallet.com wallet is loaded from a remote location. This means that whenever you use your wallet, you need to trust the developers not to steal or lose your Ether in an incident on their site. Using a browser extension or mobile app, if available, can reduce that risk.
The MyEtherWallet.com wallet can be loaded on computers which are vulnerable to malware. Securing your computer, using a strong passphrase, moving most of your funds to cold storage or enabling two-factor authentication can make it harder to steal on your Ether.

Tor can be used
