Yes, it is. But some people like to use their CC over Paypal. Some people don't even have a Paypal account. This is a common thing. Paypal works when starting up but later, you realize you are missing sales because of the lack CC option.
As you all know, unless you live in the US, it is either too costly or simply unavailable to use Stripe as a CC payment gateway. I've been using Alidropship for 2 months now and it keeps me up at night when I remember how big carts were dropped at the checkout, very likely due to the CC payment...
