Started trading on the P2pb2b a few months ago and for two months of trading I had no problems. The exchange works stably, there are no freezes and slowdowns of the site, which are observed on some other exchanges. There are a large number of coins that can be traded. The Exchange is missing some coins, but this is not a critical issue as I see that the Exchange periodically adds new coins. I advise friends to switch to P2pb2b as it is developing quickly and its community is constantly growing
