I need to add just one user field that is very critical for my case. Bitcoin address. Is there some easy way?
Yes, there is. Look in the Customize > User Fields admin section

Thanks… That is awesome.. I suppose it is quite new feature?
One more question? What does Conformation custom field mean? How it works?
And one more: How to show custom field in user profile?

Is there a simple way yet for an admin to view and edit custom fields on a user’s account?
Right now I’m database diving, and it’s not a lot of fun - but, I feel I may be missing just where these show up…
They should appear on https://discourse.example.org/admin/users/watchmanmonitor and be editable on https://discourse.example.org/users/watchmanmonitor/preferences.

Is there a simple way to edit the userfield for all or a group of users in bulk? I’ve just added a new user field after launching my forum and would want to fill this field for the existing users, currently the only way to do it is by Admin-> Users-> Click on the user’s name → show public profile → Preferences → Fill the field → save changes
then repeat for the next user 
is it possible to show the custom field(s) on the Users page along with their email address and statistics?

the links don’t work…?./>
You need to replace discourse.example.com with the domain of your site.
