# Did I do right by adding “bitcoin” as a new tag to this question?

I just made the following edit: https://puzzling.stackexchange.com/review/suggested-edits/20298

It adds the tag "bitcoin" to this question. One interesting feature of the puzzle is that you actually need to know how bitcoins work in order to finish solving the puzzle! As a result, I figured the new tag was appropriate because it indicates that specialized knowledge is required.

Was I correct in making this edit and creating this new tag?

• There was no bitcoin tag before you added it in. – EKons Jun 4 '16 at 9:47

• bitcoin is still an outlier as a topic of interest, and anyway it is a specific thing which can be easily found with a single-word search instead. For something requiring specific expertise that doesn't fit into a larger category, knowledge is the way to go. – feelinferrety Jun 8 '16 at 22:32
