I remember back in the day this used to happen with cards. A new bonus would come out and the hype would just grab people. May 2015...Citi comes out with a 50k Hilton points offer on their no AF card w/ just a $1k MSR (yeah...back in the old days Citi had a Hilton card). People were going crazy over it so I signed up... I had no need of Hilton points, it didn't exactly fit my strategy...but I went for it.
Later that month Chase puts in place the 5/24 rule...and you guessed it - that Citi card was my 5th card in 24 months. I had to pause churning on my SSN for 6 months to wait for a card to fall off to do a CF/CSP double dip (this was before CFU and CSR even existed, lol). During those 6 months my wife got 7 cards so it's not like we were on the sidelines...but still, I got distracted by the allure, drawn by the hype, and made a bad call.
So now, when something is really drawing my eye in the game, I always take a step back and make sure that the MATH or STRATEGY makes sense and that I'm not just in a FOMO mindset.
EDIT: Wow - have I been churning awhile. This post mentions a card that doesn't exist anymore, is set in the time period before the 5/24 rule, and happened long before CSR even existed... I am an old man churner, LOL!
