It all depends very much on the rules of the individual website. You must understand that the limits will be much higher at high-roller casinos than at other sites. High-stakes players make large deposits, take huge winnings, and also suffer big losses. You cant say the same about players at minimum deposit casinos, where gamblers can deposit from C$1 to C$5 and bet C$0.01-C$0.1. Everything is individual and varies from site to site. Choose the casino site that suits your playing style the most.
