Bittrex is about to remove a bunch of Coins. If you have any of those on your Bittrex account transfer them asap to not loose them.
Their News states:
Occasionally, there are circumstances that lead Bittrex to remove a coin's wallet or market from the Bittrex Exchange. These actions are taken to ensure customers have access to digital tokens that continue to meet our strict coin listing criteria and have a properly functioning blockchain and wallet.
We will be removing the wallets included in the list below on March 30, 2018. Once these wallets are removed, we will no longer be able to recover these coins. Users must withdraw their coins before March 30, 2018, in order to keep them. The coins marked with an asterisk (*) have broken blockchains or wallets that will not allow withdrawals. In those cases, the inability to withdraw your balance is not due to the Bittrex Exchange platform, but is caused by a problem with the underlying blockchain or wallet associated with that coin.
