Online casinos can reduce transaction fees for players through several strategies, including adopting alternative payment methods that offer lower fees, such as cryptocurrencies or e-wallets that often charge lower transaction costs compared to traditional banking options. By negotiating better rates with payment processors and payment gateway providers, casinos can pass on the savings to players, making it more affordable for them to deposit and withdraw funds. Additionally, implementing loyalty programs or promotions that absorb transaction fees for specific payment methods can incentivize players to utilize those options.
