Well, a year after my last increase Capital One finally decided to increase my credit line... by $100, hahah.
Started in 08/17 on my rebuilding credit journey with a $300 secured card. After 5 months, $600 secured card and 6 months after that a $600 unsecured card. They allowed me to do a product change 6 months from that point and just yesterday I hit the CLI button and they offered me a whopping $100 increase to a total $700. Yay me.
Maybe it's time to close this card and reapply? 
As you know its a bucketed card and will always be that. Yes you can try. Remember the triple pulls. But it didnt stop me after having 2 bucket cards. Then each approval got 10g's in SL's and lower APR's. But I was limited due to BK. Hey its $100 you didnt have yesterday. Congrats!
