Use good socks that match your Card's Zip Code. Set time zone according to Zip's City. Use Number where you can collect the calls (Skype etc) Use Private CC and big thing is don't use this card on any other, mean keep it live.
not feasible if you dont know what your doing. 99.9% of gift card sites will have 3d secure tech in place so you wont be getting around that without some SE work. just buy good cards and hit up non 3d secure sites.. try ccfamily.club or carders.pw for some good nonvbv cards and try hitting unkown shops or even some shopify shops work good too
