How to add the tag payment:bitcoin=yes in an OpenStreetMap editor for the CoinMap?

In addition to the other answers, please only add factual information to OpenStreetMap. Especially:

• Do not advertise your business. Facts are ok, marketing is not. You can add your telephone number or opening times, but we're not interested in "award-winning", "family owned", "finest in town", "exceptional", "awesome", "beautiful", or any other marketing speak.
• This is true for the business name as well. The name tag is for the name and nothing else; if your name so happens to include marketing speak (i.e. if your business is really called "Banana Chip Studios Award-Winning Fine Art and Photography") then shorten it (to "Banana Chip Studios") or you'll be suspected of trying to "spam the map".
• Do not add a business where none exists on the ground. We are not interested in the location of your mailbox or your registered address if you do not have a physical presence there (a workshop, a shop, or at least an office).

"go to OpenStreetMap editor" means that you should edit our OpenStreetMap data (apparently coinmap uses it). Read our Beginners%27_guide or http://learnosm.org/ to learn how to start editing OpenStreetMap. If you feel like you want to start right away, go to https://www.openstreetmap.org/user/new (or click the "sign up" link on the top right on your homepage).

If the shop you want to edit does not exist yet, you need to add it to our data (see the beginner guides for this).

For how to use "tags" see Tag#Use_in_an_editor.

Welcome to OSM!

To be clear because this is a frequent mistake:

Tag a key name of "payment:bitcoin" with a value of "yes"

Do not create a key named "payment:bitcoin=yes".

I was also confused how to do this..

Check out this tutorial. http://www.youtube.com/watch?v=FLpe8YDf8P0 This makes it clear how to add your location on the Coinmap.

Hi, take a look here http://www.openstreetmap.org/#map=19/52.08724/5.12155 and tag the shop or business the same way as Sociabol.
