I've been playing at ACR for a long time, and anytime I would deposit, if I wanted to just make a small one, I'd have to do it for 50 bucks, since that was the limit it said. Well I was talking to support one day and brought up the question of why there limit it so high compared to other sites (I thought he'd respond with stuff about credit card fees and processing fees) but he actually said that it's not, that the minimum deposit for your first deposit is 10.00, and for any deposit after that is 25.00. So I gave it a try for a deposit of 25.00 and sure enough, it worked! They just set it higher in hopes you deposit more at their site.
