What is the payment method? Is it BTC? If it is, it is better to adjust to the lightning network due to the smaller payments, all your money will be lost when you try to send that money (High payment fees.)
Will more countries be added?
Can I re-verify the number? Or is it for once (OTV.)
Although the value is low there are other services "Smspva" that offer the same service and at lower prices, are there any advantages to your service give?
