I froze my credit with Equifax for now. I'll evaluate what I want to do before their "waiving of fees" ends in a couple of months in regards to freezing at the other bureaus. I love to churn, but I'm on hold for a possible mortgage next year anyway, and worst case scenario is I have to deal with ID theft right when I want to move.
Churning has been awesome. But many of the "good" bonuses I can't get for another year or so anyway, and I have enough spending thresholds or targeted spending bonuses on my existing cards to keep me occupied.
