I hold some block on bittrex which I bought few weeks back, I got an email from bittrex that read you're holding some coins that are due for removal on 30th March , while i hold only blocknet and negligible amt of btc, I did go through the list of coins on bittrex that will be  removed and it doesn't include blocknet, Iam not able to figure out why am I in receipt of this email, am I missing something here? Am I the only one who has received this type of email?
