<prompt> Human: Im REALLY sorry if this is a dumb question, I never had any education on credit cards other than what Ive read here.Im early 20s, if that makes any difference. My first card was a 500 secured credit card. Things went great, used it for everything and always paid it off. Ended up paying only 12 in interest the first year I had it.Then one day it stopped being secured, they released my 500 for me to use freely. Awesome!Then, suddenly, my credit limit jumped to 1000. what the heck? I asked my mom about it but she just said now you can spend more! Yeah right.Anyway, I continue on the same path, use my 1 card for everything and pay it off every month. 0 interest paid the next year.Now I just checked it today, and I suddenly have a 6000 limit! No Emails, no mention of it. Is this normal? Its over 1k more than my emergency credit card. It seems a little abrupt...Anyway, thanks for any help, Im just a bit weirded out when something happens to my cards that I didnt do myself.Assistant: what card do you have so I can jump on that bandwagon? sheesh. its definitely not a bad thing, just means theyre rewarding you for using your card responsibly. has your income changed recently, by chance? Human: Navy Federal nSecured. Im happy with it, so far unstolen and I get reward points. Im almost to a 50 visa card!Not really for the best. I got a job, lost a job, got a job, now Im looking for a job.  <response>: One thing to note, most secured cards offer little to no rewards. Now that youre got some decent credit you should probably shop around to see what kind of ratesrewards are out there.-Thats assuming the account didnt change and they just raised the limit on your secured card.
