I am not dragging comparisons to this two payment gateways, but they look alike when it comes to being faster for transactions and they are both secured. But PayPal is very much popular than payeer, and it is more adopted by online businesses than they make use of payeer.
PayPal has enticing options especially the charge back option, which you can make use of, to recover your funds from a scammer when he or she tricks you and carry your money away. You can simply initiative PayPal charge back and funds returns to you.
Payeer is fast, with low gas fee for transactions. It has option of cryptocurrency where you can convert your payeer fiat currency to cryptocurrency and withdraw to any wallet of your choice.
Which one works best for you?
