how to correctly use cc and cc site

[gvv]

i tried brainkreb,unicvv,and mc-souese site.the most shit is brainkreb,even holder and address is wrong,elso site validity is about only 20%.
i bought 1000$ and 30 ccs, only five have available balance,but all result is cancelled and failed by amazon,g2a,bestbuy,mygiftcardsupply,thegiftcard etc.
my god,i now suspect if carding can make money,everyday checking and selecting several cc then matching ip for it,registering email and warming site,beyond all question,outcome again is failed.again waste a day.fuckkk.
Is everyone have alike manner with me?so inefficient? or i have not find a right site?
thank you and merry christmas!
