You should have at least two if you're a responsible person. Got to have a back up card cause you never know what could happen.. You could be out of town and become the victim of credit card fraud which you would have to freeze the account- and if that's your only card then you could be f*cked. Or if say for example you have a Chase credit card but you have issues with them and they close the account, you're good cause you have a Capitol One or Amex on the side so itsgot 3 credit cards.....at 30, i think 1 is good enough.....
i get signup stuff from american express, discovery card, capitol one in the mail, i tear the sign up part into bits and peices and throw it away............![]()
Have two cards from two different banks and two different networks. like if you have a Visa, make the next card or backup card a Mastercard or Amex.. or vise-versa. Sometimes networks go out or get hacked as well.
