Sure. I prefer to keep getting it thereby getting free fuel for my hobby of credit card signup bonuses.
How do you make the spending requirements on those? If I'm doing some large home improvement project, sure, but for normal spending, even if we put literally everything we could on that card (we tend to shop grocery stores that are cash/debit only), we wouldn't hit the requirements a lot of the time.
You either:
1) Go for cards with a low spend/high percentage return (for example, the current offer on the Bank of America Cash Rewards is $200 back for $500 in spend)
2) Find some other way to increase spend/throughput on the cards.
Example 1: We pay annual car insurance, house insurance and life insurance in the fall via credit card. So, sign up for a premium card a month before insurance payment time.
Example 2: I can pay property taxes with a credit card for a ~2% fee. Say I have $5k in property taxes and a new Chase Sapphire Preferred. I put $4k on the card to meet minimum spend.* That costs me an $80 fee, gets me $40 in points and a $500 signup bonus. Net is $460 for a single transaction.
*Okay, technically I could pay ~$3925 in tax, plus the fee to make the $4k min spend.
Example 3: I can put almost all of my utilities on credit card payments.
Example 4: I sometimes travel for work. Rather than get a travel advance or use the company credit card - I have the option to use a personal card and get reimbursed.
Example 5: Stop having withholding of federal income tax, do quarterly estimated payments to the IRS via credit card. Fee is a bit under 2%. Note: I haven't done this one myself.
Example 6: With some mild risk: Buy gift cards for spend you would do anyway, but would be outside the timeframe of the bonus. ie, you know you spend $300 a month at Costco (or Target, or Walmart, or whatever) - so before the end of the min spend period, you buy ahead another 3-6 months (or whatever) of expected Costco spend to meet the minimum. What's the risk? Typically banks don't want you to buy gift cards to meet minimum spend. Usually it doesn't matter, but being blatant and getting eyes on the account may get the bonus revoked.
