Hello Everyone i just wanted to share a little story with the community. Here recently i started playing online poker again at betcoin.ag. Well i went to login and realized i had forgotten my login info and went to make a new account. Well later that day i was playing on the new account and was in the daily coin 1 btc GTD tournament running pretty good and ended up getting 2nd place for $300.00. Went and cashed out $250 and left 50 to play with the next day. Woke up next day and noticed my cashout did not arrive. I checked my account and could not log in, so i went on live chat and they told me i was banned and my funds was taken from my account by management. Please Everyone beware if you are playing there. I always trusted them and never thought they would go this low to steal my funds. I have since then been unable to get my bitcoin. They seem to be doing allot of shady stuff to people recently, not paying out tournament tickets and keeping peoples bitcoin. Please be very carefull with your business there !!!! 
They banned you probably on the suspcion that you are using multiple accounts to abuse tournaments and giveaways.
You should really contact them right here on bitcointalk though and see what they can do for you. They haven't had the best reputation on bitcointalk though, if i remember correct they are in the red at DT2 for previous shady dealings.
Always be careful when playing with 2 or more accounts. Their terms and conditions probably prohibit that and if you are dealing with a dishonest admin somewhere then they are likely going to be using that as an excuse to not pay you out.
