Is it a good idea to get a credit card 10 months after getting one?

10 months ago I got a Wells Fargo card for a balance transfer so I have 1 hard inquiry on my credit report right now. I am 10k in credit card debt and just made a $2500 payment off that hasn’t shown up on any reports as of yet, my score is currently 721. I have a budget plan going and expect to pay off all cc debt by March of next year. I’m wanting to get a chase freedom unlimited card because I have outstanding approval odds. My laptop just went kaput and I’m wanting to get the card to buy one because I will get $250 cash back bonus from the purchase and will have 15 months to pay it off which will work really well with my budget plan. Is it a bad idea to do this?
