what do you think about the way credit card works . Due day , pay 10% minimum bill and continue interest per day , and you're settled for the month until next month's bill , and so on so forth .
I've used the minimum pay to avoid screwing up my credit report several times .
30 day cover at once not only screw himself , but screw the market too , put more down pressure on BTS if it's on a bear market with thin order book .
also charging daily interest after minimum pay earns interest (profit) for the system by lending extra leeway to the shorter after 30days , works like a bank .
In China , banks are currently earning 1.5% interest per month on credit card , that's 18% APR , big profit for the bank .
