I am 30 years old and I’m looking to get my very first credit card. I’ve looked at discover and capital one. I currently don’t have any bills but I would like to start earning money back because I spend about $2000 a month. I would like to start traveling in the future but I know I am not able to get a travel card like venture x or chase sapphire. Which card would be a good gateway to a better card so that I can get travel discounts in the future? How long would I need to use the card until I can apply for a better one? I’m thinking I should just go with the capital one so that upgrading would be easier.
