Those amounts should be going through fairly effortlessly if you have good cards, but as I said above: carding anythin digital can be difficult for even professionals no matter the amount. I'll give you a few more tips free of charge though:
-buy some aged emails. many merchants of high risk items use a product called emailage to get information on an email address and this includes when it was created. any newly registered email is deemed high risk for any merchant who will be a target for fraud (sellers of electronics,digital items). you can find aged emails on any online marketing forum
-Visa and Mastercard networks do not verify the name on a credit card, so you can put whatever name you want in the name field on an order form. If you buy some aged emails and some of them have a name in them, just put that name in the order form and you'll see a higher success rate. Obviously if the merchant calls the bank to confirm the transaction then it'll be declined, but this doesn't usually happen as long as everything looks right
-Amex cards are the exception to what I said above. they do verify the name, and they tend to have higher security than visa and mastercard, so I normally avoid them.
-You mentioned wanting to try a centurion. Why? Try thinking about this process rationally-why would anyone with a centurion card try to buy a $50 game code? that is much too cheap for someone with such a card. success in carding comes when you successfully impersonate the individual, and this can be done so long as you use common sense. If you're looking to purchase something like a $50 code, then use a standard credit card and maybe you'll see higher success
-Do you have a good burner number for verification calls? This can be crucial in many instances. A good number mind you-not some virtual shit.
-5socks is a good socks5 provider. How are you using the socks? I like to use the software proxifier and run everything through that as mozilla can leak stuff randomly I find. Are you checking for DNS leaks? Go here to check
http://dnsleak.com/ you can enable "resolution through proxy" in the proxifier settings to use that proxy's DNS
-Use getipintel.net to check the fraud risk score of the proxy you're using. Anything above 1 I tend to just scrap and replace. Use ip-score.com to check that your IP is not on any spammer blacklists.
-Are you changing the time zone of your machine before you card? If you're on the east coast USA and you're on a California IP, but your computer's time zone is EST then that is obviously a red flag. Make sure to change this
-If all of the above sounds like too much work for you, then maybe you can try phone carding using the 4G data network. anti-fraud networks do not typically blacklist such IPs as that would be unfair to the many legitimate customers that rely solely on their phone data. You can get a lot of success just doing this
-There's not many hints I can give you in finding the right bins as it's mostly a solitary struggle for all of us. You have to experiment and just be smart. Eventually you'll amass your own list that you can do a lot of damage with. Keep notes on the bins you card with and maintain that list. Update it everytime you card
I hope this helps
