Today I was thinking about my recently ordered Ether. I didn't get any notice that they were added to the account I usually use. I made the research and found this:

Regretfully, our server (root account) was compromised two days after switching web hosting providers. We are still investigating how the attack happened. The majority of the Ether was moved to: https://etherscan.io/address/0xef9e06ee6c6adde29237e55a20e6743c92575ebe by the attacker. An attacker has moved most of the Ethereum on the website, but thankfully we have managed to recover a portion of it from low balance accounts. We will be announcing a user reimbursement plan soon.

Erm, what?! I really regret not to buy that Hardware Nano Ledger S or have an offline wallet. Why I was always buying more and more coins, but didn't care about my ether online wallet? There are some solutions to store your ether in an offline wallet.
Big, big mistake on my side. Now here I am and I can only hope, that all the coins are recovered in the next weeks, like the owner of the wallet-site is promising. Keep fingers crossed.

I give you the advice to store all your coins offline and back them up. And don't forget to have a copy of your backups in another house! A fire can destroy everything.
