Here's the case, I have an Amazon credit card issued by Chase with $2000 credit limit. And I use it a lot through purchasing the products for others and retaining the cash back myself. I spent roughly $20,000 each month on this card. Every few days when the credit limit runs out, I pay the debt through my chase checking account and the credit is released again. But I do this carefully to ensure that before the statement day, the balance is $0 on my credit card, so I can make the credit report looks good.

My question is, how does this kind of behavior affect my credit report or my relationship with Chase? Will I be granted more credit if I apply a credit increase in the future compared with someone who only spent $1000 through the same card? Will a have a higher credit limit if I get approved for another Chase credit card in the future? Will I have a better chance being approved for a new credit card by Chase or some other company because I make a lot of transactions and profit them?

Thank you.
