So, be careful when an online casino suddenly suspends your account, asking you to confirm your identity. Often, the data is sold in the 'black' market, or the casino themselves use it for dubious means. Scam gambling sites usually ask players to provide unnecessary personal data. Although online casinos make a small percentage of the amount, it is still worth noting that rogue casinos can steal your financial data. According to research done in 2017, online frauds stole $107 billion from people worldwide.
