The cards were dumb, but I wasn't at all surprised they sold out.  Trump has a giant fan base.  His fans go from the super-rich to the super-poor.  I very much doubt that people who are screaming about high gas prices, or are genuinely feeling the effects of inflation, scooped up these cards.  I rather think those that purchased these cards have money to burn.  

At the same time, I do not believe that out of those buying these cards, none have complained about inflation.

As you yourself said, everyone is crying about inflation. And yet a lot of people had the spare cash to fritter away on this.

I read all 45,000 of them sold out in 12 hours.  How many buyers that translates into I don't know.  I read on CBS News that the cheapest ones are now fetching $650 on the secondary market. 

I don't know much about these NFTs.  Seems quite speculative.  I'd imagine if Trump gets reelected these things will skyrocket.  

e.g.  Acting Deputy AG Richard Donaghue's testimony about a conversation he had with Trump on 27 Dec 2020 "The President then continued, there are 'more votes than voters' and I said, you know, that was just a matter of them comparing the 2020 votes cast to 2016 registration numbers. That is not a valid complaint."

Trump then on 21 January 2021 spoke publicly about "More votes than voters. And many other states also."
