I was always wondering what could happen if myetherwallet.com website get hacked... so it's better to have the coins on a desktop wallet, instead of a web wallet?
It's a question because I a little bit afraid of web based wallets
If the website got hacked and there is a possibility for the amount in the wallet to be revealed. I can say that was better to have your coin on the desktop wallet, But as far as i know that will not easy to hacked themew wallet, many people are still save their amount in there and the team always update the security of the forum.
There is nothing to hack on MEW website, they don't keep your keys.
Only risk is if you go to a fake MEW website.
