Yes. Be careful about Polo. If you read their update from 3 weeks ago, they wrote they shut down their trll box because they could not handle the support requests.

It took them 30 days to send me my small amount of lite coins... finally got em and sold just in time ebfore the crash of yesterday....

If you are holding long term on your coins be sure to have a wallet on your pc/phone and make sure you have 4 or 5 backups of the wallet.

If using an exchange you have to play the risk game. Sometimes they won't let anyone withdraw. Othertimes some get hacked. It sucks, Ihave been through all of this. :(

Good luck on your issue though!
