The most popular online encyclopedia mentioned cryptocurrency in its guidelines for editors. Now if an author possesses bitcoins or altcoins, it may cause a conflict of interest.

The popular free Internet encyclopedia Wikipedia added cryptocurrency possession to its article about conflict of interest. According to the updated guidelines, if an editor possesses digital currencies it may be an obstacle for creating and editing unbiased materials on cryptocurrency topics:

"Any external relationship—personal, religious, political, academic, legal, or financial (including holding a cryptocurrency)—can trigger a COI. How close the relationship needs to be before it becomes a concern on Wikipedia is governed by common sense. For example, an article about a band should not be written by the band's manager, and a biography should not be an autobiography or written by the subject's spouse," reads the new version of the article.

The main problem posed by a conflict of interest is a possible prejudiced submission of materials.

"The content they add is typically unsourced or poorly sourced and often violates the neutral point of view policy by being promotional and omitting negative information."

Some articles in Wikipedia, including those about cryptocurrencies and related technologies, are characterized by unnaturally large number of corrections introduced. In extreme cases, this can lead to a complete or partial blocking of the page with such material, so that anonymous authors do not make changes that distort information in a favorable for them way.

One example is the article about Bitcoin Cash. The page contains a warning that the neutral nature of it is disputed.

Any user can create an account on Wikipedia and become its editor. This was done already by 33 million people, with 140 thousand of them being active editors. These enthusiastic volunteers update and verify the facts of the published articles. While the English version of Wikipedia contains 5.6 million pieces of information, checking all authors for a lack of conflict of interest seems difficult.
