Is keeping old credit cards and opening new credit cards with high limits and never using an ideal way to boost credit scores?
I disagree with the reply.   Your both impressions are correct. -   Do not close old credit cards because they keep your credit rating high (fico score) -   Also low utilization that credit cards report to credit rating companies, improves your rating.
