I think it's really normal cause there are so many tokens from airdrops and bounty campaigns which never being listed on any exchange but I think you should try to sell them on Forkdelta or Etherdelta to see if there is anyone wanna buy these tokens
. About price of tokens much lower than ICO price, I also think it's also normal as well cause down trend is happening and it's the main reason for this case but it's not the only cause token has low price when listed on exchange than ICO price also can because of bad project
