is someone accept credit card as payment option for trading, I will like to buy bitcoin
There are a number of exchanges and websites where you can buy bitcoins with credit card but buying bitcoins with credit cards might be fatal to start trading. Credit cards charge you a percentage of fees for making any purchases and few peoples might find if beneficial because you can make higher profits by trading with bitcoins and can easy pay off those interest charged by the credit card companies but this is what might make you land into loss.
You really need to be a experienced trader in order to make fixed profits and buying bitcoins with a credit card is actually a risk for all the peoples who newly start trading because price change might also land you in loss and you might not even be able to pay the interest along with the principle which you borrowed from the credit card facility.
