First carding attempt was a failure

[bg12345]

Hi everybody !
I'm learning how to card and yesterday i've try to card for the first time, and the payment was not accepted
My drop is in Eu and i try to order with usa cc, i think the problem is here, is there method to pay with usa cc with drop in other country ?
or it's a waste of time i should test with the drop country cc ( there are more expensive than usa cc )
thanks
