High-stakes gamblers typically prefer payment methods that offer speed, security, and privacy. This includes options like cryptocurrency, particularly Bitcoin and Ethereum, due to their decentralized nature and reduced transaction fees. Credit cards such as Visa and MasterCard are commonly used for their convenience, although some casinos impose limits on withdrawals via these methods. E-wallets like PayPal, Skrill, and Neteller are also favored for their quick processing times and enhanced security features.
