I personally dont like the idea that a user must first create an account on Payeer in order to pay for the service, its just one additional hurdle, at least in my opinion.
AFAIK there's no need to create an account on payeer, it works like bitpay and other crypto payment gateway. The user only need to pay to the address/QR shown on the payment page.
Worst, payeer blocks US ip address I'm using and telling me
Sorry, due to AML policy, we do not provide any services for US citizen at this moment.
Funny thing, your minimum service offer 25$ with current rate of 0.002463 but payeer only accepts payment minimum of 0.0025 BTC

Thanks for your interest in our service, if you want to order i can give my btc address to pay or if you prefer you can pay with Paypal (family and friend only). Just send me a PM
