We want to open a gaming business for Asian countries - Japan, China, and Thailand. What payment systems do you think will be convenient for this region? Thanks in advance.
If you'll use crypto then a normal crypto payment gateway would suffice but if you want to accept and send money thru their local fiat then search for those countries' local digital wallets (regardless of being a crypto supporting or not, you can still take their gateways accept their fiat then just convert it to your end). There are no such thing as Region-based payment system. If you really want a crypto-based payment system, then go chat all of existing platform's chat support then ask them for what gateway are they using.
