The one I'm looking for shows the spike from two years ago, but on a chart that extends all the way to today. I felt like it was a OP_RETURN limit remover who posted it with a little arrow at the end ...
Old (only up to mid 2023)
But shows the two years ago spikes.

Why do coins still exist? Couldn’t we just agree to round up or round down collectively and just do away with them? If something cost 5.05 just pay 5. If it’s 5.51 just pay 6. Should balance out ...
They got rid of pennies like that in Canada a few years ago. Round up or down to the nearest nickel.

Cashu is amazing.
I don't see lightning be used for very small payments in a bit so distant future. This things is the closest thing to actual cash in an actual wallet.
Analogies.
Cashu is every...
Will you be paying by cash or card?
Experiment of the day, the QR code on that NFC tap card isn't sats, its a public key for my Cashu.mewallett. Meaning I can request locked ecash payments that only I can claim, even while I am offline. (P2PK).

Yes also curious about the overall size needed?
The cards I have can store any low 2^x (64 wasn't a random choice).
If the number of sats was written in binary... And if it only needs one ...1. 1,2,4,8,16,32, etc... It seems to use ~246 bytes.
If you need two binary 1's, such as 3, 5, 6, 9 uses just under 400 bytes.
If it needs 3 binary 1's (7, 21) it blows over the 500 byte limit of those cards at ...526 bytes.
The number 256 is fine at 246 bytes, but 255 (which requires 8 binary 1's) needs 1.257 MB.
The 2-to-the-power-of-trick, breaks down at 512 as that now needs over 500 bytes too.

Which NFC card is that?
Cheapest (and coolest looking as a bonus) ones I could find that had at least 500 bytes of storage.
"Timeskey" was the brand.
