I plan to cash some Amex pts at 1.25 cents via Schwab in a few years. I think this is a good deal if just sitting on good size stash. Earning just 8% return or so on the money means 1.35 value after one year, approx. 1.45 about 2 years, etc. So if too much excess points, jettisoning some seems prudent.
I struggle to find the value with Amex in my situation to make the points that useful except with nice transfer bonuses like 50% BA. I have so many Citi TY for Singapore. 100,000 Amex bonus is $1,250 cash and you can only get 1 cent for Chase points, that are far more useful for United, Hyatt and the soon to be 1.5X for travel with Sapphire Reserve in hand.
