It is very hard to know for sure what will happen next in the online gambling world. So far this year we have seen some of the biggest online poker sites get pushed out of the US market.
More recently, second line US facing poker room Doyles Room had their domain seized in a similar fashion, but they have not withdrawn from America just yet. It remains to be seen what they will do in the long run though. In the same Government action, some sports betting sites were also hit.
One of the best pieces of gambling advice that you will ever get is this: when you are depositing at an online casino and you are not intending to claim the bonus on offer, then you should alwyas make the minimum deposit allowed. This will allow you to test out the deposit and withdrawal procedure before committing a large amount of your gambling bankroll. You can get a list of minimum deposit casinos here.
