I've been using Livecoin for a couple of months now. Deposits and withdraws are a little slow, sometimes depositing bitcoin can take an hour to reach the wallet. Likewise, withdrawals are reliable but I've seen other exchanges process them much more quickly. All in all though I like Livecoin and I happily use them 4 or 5 times a week for altcoin trades. Recently I have had issues with DIBC on Livecoin, frozen wallet, halted trading and no information about when trading will resume. Locking over $200USD of coins down and preventing me from sell or withdrawing the funds/coins. I blame DibCoin for that is the most part but Livecoin have been very unwilling to update myself and others on the coin's progress after 2 weeks of locking the assets. I'd give Livecoin a 7 out of 10. It would have been a 9 if not for the DIBC mess with have been part of for the past 2 weeks.
This site is really live. They have real time buyers and sellers in which I have done a few transactions with.
