I'm just glad that we can finally talk about Fold without the 'real bitcoiners' making fun of us! 
Been using fold for two years now, but still have my costco citi card. I get whatever % back from them in cash at the end of the year, and pay the citi bill each month (in full) via the fold card, and get another .5% on that. 
I do all my amazon purchases via gift card now as well, which those you get 2.25% on from Fold. Other bills get paid via fold as well at .5% . Not as lucrative as it was 2 years ago, but it's still free money. Actually, way better than money.
