What can make a token in MEW disappear?
lately i heard from some friends that he lost the token at MEW, he said that he had entered on the right site ie
https://www.myetherwallet.com/which is happening is exposed to phishing, is there any other cause besides phishing?
It is not that tokens are being stolen everytime. Due to excessive load on MEW server, they added a restriction. To view all balance, you need to click "Load All Tokens". In meantime, it's best to view your wallet on etherscan.io or Ethplorer. If you still don't see tokens on your address on either of these, is simply mean your wallet is compromised. No fault of MEW.
