I also got NPX token from ICO and also I bought some more on Fork Delta and IDEX. Its interesting that you received the token 50 days ago and yet, it doesnt show up on Etherscan. Its definitely not hacked because that would mean it would be transferred out of the wallet. You said it doesnt show up on your MEW either? But it should be there. I checked the contract address and thats accurate as well. But good to know you also have some FRIENDZ token btw.
