It would only make sense if you kept the page open without refreshing, and that sounds useless.
I do this all the time
Of course, I know that feeling, same thing on my browsers
but to track the price of Bitcoin in the past is completely pointless.
You and I are familiar with this feature, so we can see that it is an image generated when the page is loaded. But I believe that there are thousands of readers who are unaware of this resource, and have no idea of how the image works. Furthermore, due to cache issues, the image may not be reloaded correctly, and this will result in an old image.
That's why I think that this information should include the update date, ensuring that the reader receives all the information, whether they are familiar with this tool or not.
But, it's just my opinion, if the majority thinks this feature is not necessary, it's not worth Bitmover wasting time on it.
Earlier I proposed a similar feature. Maybe not as part of the current one, which already has its purpose, but as an additional one.
If you leave the page open, the image will not update by itself. You need to reload the page/image, then the data will update.
That makes sense. Nobody would expect images posted on a forum to update without reloading the page.
But it would be nice if the timestamp can also be displayed. That would remove the doubts for someone who just reads the whole context without knowing how the thing works.
I would not ignore the purpose of this without an update after each refresh. There are situations where it is necessary to know the value at the time of writing the post.
