Oh sorry about that.. there are issues with Poloniex as many complaints the transaction is struck down.... So many people's experienced different using it.. but lately many user's shifts by making use of bittrex as an alternative to carry out some transaction tasks.. but since my account was not verified with them despite provided all the required details still they complaint it's blur this and that a friend advice me to use coinbase.com which is good suggestions that has features to exchange SBD or Steem and can help trasbatc into your Bank account , but unfortunately there are regions that the service is not working... Si I give up using it... During my findings one that could be use I came across https://www.bitstamp.net . This is really a nice exchange site.. their location was at Luxembourg in Europe ... They have established and operating for long. But I will suggest you should read their terms and regulations for your country since you are in Europe.. they kinda difficult to use coz of tax.. but for you that living in Europe it will make sense using them..
