<prompt> Human: So Ive had a credit card for 4 years now. I also recently opened up another credit card. Credit score is 800.Credit Card 1: 4 years old, 9000 limit.Credit Card 2: 1 year old, 8000 limit.With credit card 1, Ive always asked for a moderate bump to my limit. I think I ask for 1000-2000 more per year. The purpose of me doing this is to reduce my credit utilization for my credit score. Should I continue with this strategy? Ive never been denied a limit increase, but Ive also never asked for a dramatic increase.  <response>: Recently increased my limit on one of my cards for the 5th time in 4 years, this time by another 5k. I explained that I want to continue to grow my credit score and thought it would be easier to increase my credit limit on my xxx card instead of getting a new one with a different company as I prefer the ease of working primarily with my xxx card.Do I still churn new cards that work better? Oh yeah. But Ive found this has become my go to statement when asking for increases on my cards.edit: Better phrasing on my opening line.
