I have been using p2pb2b for 3 month now. Trading can be done very easily and its based for professional traders. The charts are good and p2pb2b does a good job providing good support for any issues. Very open process and really good job done here. Overall p2pb2b is a very user friendly exchange with a very good community, for example they host Bitcoin Forks Battle and the best 2018 meme contest! Thats a lot of fun and coins can easyly list for free if they win the vote battle.
