Probably nothing... https://globalnews.ca/news/8760673/nft-jack-dorsey-tweet-sina-estavi-48-million/amp/ At least the 280 bucks will pay for his monthly internet service... Lol...
A loss is only a loss, once you sell it. Man should have kept it, and try to sell for $50 Billion or something.
It clearly states if you scroll down a little he can accept or reject bids so I doubt it would've been sold for $280.
Same happened on few other attempts. When the sale/auction happens for real money and not wash trading hype, there is not much market for the most of them.
Whether he sold it or not, he now has an idea of what it's actually worth. Realized or not, still a huge loss. (Of course that won't matter if he's a crypto million/billion-aire.
But is it true? Do we read the whole story? -my neighbor is a pilot and he says everything in the newspaper is true, except stories about airlines-
