So, I didn't understand your criticism of my suggestion.
Logically, the way I presented the idea, it doesn't have to be exactly like that. It can be done another way. Basically, the idea was to present, together with the value of BTC, an indication that it was updated at this time. So as not to get the idea that the value presented was that of the date of the post.
We are talking about the same thing. I had a similar idea earlier but executed it in a completely different way. Even without generating images, just as text. Who knows, maybe I'll realize that someday.
