Have you ever experience that your token or coin are sent to 0x0000000000000000000000000000000000000000
address without your knowledge?
In my experience someone maybe inside my etherwallet have move my token to this address,
i mean whose fault is this, but my other coins where not even touch,
here is the image,

In some post i saw people posting that they accidentally sent it to an empty address
but in my case i never open my account, have this happen to anyone?
what are are the precautions you have done
It never happened to me for more than six years that I am using myetherwallet, it will be best if you will double check your private details especially your private keys because there is a big chance that someone has your private keys and do the transaction.
You can ask your families,friends or anyone that you know that can access your computer,cellphone or your gadgets where your private keys are sitting. Sending to that kind of address is like burning the tokens, that what I saw when some of the project owners burn their unsold tokens.
