I've been in the game since call it 2012/2013. Things are definitely getting tougher and I'll definitely be pruning some cards from the wallet in the next year. I'm starting to focus more on maximizing spend on my existing cards, since the sign up bonuses are getting more elusive. Also I'm not wasting new cards on good bonuses unless I either need them, or they're ridiculously good (100k Plat, 35k SPG, 70k Ink, fit in this category)
