If you churn credit cards ( which is the process of making the minimum spend in a short period of time to get the Bonus points or miles ) you will usually be closing your credit card along time before it renews to its second year ( so you can start your next churn! )
If the credit card has a Annual fee , then you actually don’t use it for the full year , your provider might refund pro rata the difference. Some providers just refund the full amount!
