UK zone = Big fraud place ( London mostly ) that why 90% of USA bins was locked there .
Try swipe there 101 locally skimmed ( best way ) or work with EU stuff .
Atleast You have trick too use 201 too , ( already explain on forum ) .
USA 101 work well Only when Base was fresh ( means u are on the first circle of buyer who use new base ) but after 100pc used from Bin ( all over the world ) Bin start to be locked again ....
ex: 546616 ( citibank world USA 101 ) mostly Open all over the world for the 100 first dumps used from new base ... But after 100 used start lock in major place ....etc
and real Carders ( who know the game ) already first to get such bin and use when is good , so when noob and later buyer try then always got decline/lock
too TS :
People do carding as lifestyle , they can bring $$ due too a lot of work ,study,risk,time for that . Work Hard and trust just ur mama , becoz free bins open never fly over forum )
