# 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

I don't think there's anything wrong with it, but I wouldn't have added it. My guideline for when to add tags (which could be very different from other people's) is that they should be added when:

someone might reasonably want to either...

• see only puzzles with that topic, or
• filter out puzzles of that type.

A tag doesn't seem like it would be useful for either.

• bitcoin and privacy related questions are becoming more popular across stack exchange. Although the number is small, I expect some people WILL use the bitcoin tag to search for puzzles in that category. – studycrypto Jun 8 '16 at 22:26
• 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
• I would add a third reason to Deusovi's list: There are at least 3 (T.B.D.) questions which could use the tag. There is not much sense in creating a tag for a "group" which basically consists of a single member only. i.e. if it turns out that there are indeed many puzzles which would belong to "bitcoin" then I would consider adding the tag. – BmyGuest Jun 9 '16 at 12:50
