Hide or remove tokens from your personal wallet will not work, the only thing you can do is simply send them to your friends or to the Ether Delta exchange, in the hope that after some time your tokens will cost something.
indeed can not hide your assets because when everyone knows the address of your wallet there will be many people who can find out how much your estimated assets and whatever tokens are in your wallet, if you change a new wallet it will also be like that because it is the blockchain technology that transparent so there's nothing to hide.
