The advantages of Amex Gold Card are two.
One - it is a charge card. Suited for those who always pay the monthly bills in full and who doesn't go in for EMIs. Like me.
Two - based on this (or any other AmEx) CHARGE card, you can get AmEx cards anywhere else in the world. No need of any local credit ratings. This facility is NOT available if you are holding regular AmEx CREDIT cards.
So, consider the above two points in deciding before you apply for AmEx Gold Charge Card.
