Few days ago, I logged into my email and found a email from myfico scorewatch that my fico score increased 15 points, to 601. today, Orchard bank sent me a email extending a offer for a premium visa. sure enough, it is a premium visa offer, seeming like I don't have to secure it with my own money like my first orchard bank mastercard. Should I go for this? Will this help my credit score go higher, or will it plummet like a rock? I'm not "desperate" for credit, just looking to improve it more and more, and it's seeming like to me a credit card that doesn't have to be secured is starting to show that banks want to trust me again..
thoughts? yay or nay?
