Historically speaking...
So I'm relatively new to the earning through the hobby of credit card sign-ups. It's been my main source of points in the 4 years I've been doing this. With the advetn of the 5/24 from Chase and the 2/3/4 from BoA - is this par for the course - the cat and mouse game of issuers trying to prevent people like us from taking advantage of their offers; or is this a sign that issuers will forever be stingier about how many people 'take advantage' of their products (total nunmber of cards, or churning) I'm just looking for some historical perspective on this since I'm a newbie.
