There are a number of precautions to take when playing at an online casino. First, set a limit on the amount of money you can spend on the casino. This should be a monthly or weekly limit, and you should stop as soon as this amount has been depleted. You should also look closely at minimum bets before playing. For instance, a 5 Euro minimum bet is likely to result in an uncontrollable spending spree. The best online casinos will allow players to set spending limits, support multiple currencies and fast payouts.
