A visual representation of something is not that something.

A visual representation of the timechain (the Bitcoin blockchain) is not the timechain.

A picture "on the blockchain" is not even a picture since the transactions supposed to act as pixels in the picture must be ordered in a certain, arbitrary way to do so.

Therefore, THERE ARE NO PICTURES ON BITCOIN!

Pretending that sats can be ordered this way is a bit like buying 10000 pairs of socks at H&M and then ordering the receipts for said socks in a way that forms a picture. The whole 100x100 sock-receipt-grid has nothing to do with the socks themselves or H&M's payment systems.

Not only is the notion of "owning a jpeg" absurd to begin with. The picture isn't even there! It's all play pretend!

So no, no one mined a block with a picture of Donald Trump in it. Stop pretending that happened. It didn't.
