Realized I can make Amex payments using my Fold card (via paypal bill pay) to get an extra 0.5% back (previously only thought this was limited to Citi cards). Kind of nice to get an extra $5 in BTC rewards to make payments.

Playing the credit card churning game this year for fun and this might further entice me to keep the Amex Gold long term even though it is an annoying coupon book.
