“The more important question is, “how many credit cards can you handle?” The answer to this question will vary from person to person. This issue is less about your age and more about your personality and readiness.
Some people shouldn’t even start down the credit card road at all, while others may be able to handle several cards. I’ve even seen some people successfully juggle over a dozen! You’ll want to consider your propensity for spending money if more credit is available to you and whether you are good at juggling multiple payment deadlines.
Don’t open a new credit card only because you feel like everyone else is doing it.
Having multiple credit cards is not bad if you can handle it. Different credit cards might come with different benefits and features that you may find beneficial for various aspects of your lifestyle and goals, like loyalty program status, travel-related benefits, cashback, or a sweet welcome bonus.
In addition, having multiple credit cards might help you improve your credit score, as responsibly maintaining numerous lines of credit generally fares favorably with lenders.”
