Hello, I see you are thoroughly reviewing my work, and that's good; it helps us fix what we might be doing wrong. In this case, the source tag 'local knowledge' means that I have extrapolated information from several sources, including that of the business owner, so I can confirm that the place exists in reality even if I haven't been there physically (you can see the #btcmap guide regarding this, which follows OSM rules).

As for the verification of the node at the time of its creation, I have always used the check_date tag, and when it is verified by others who fill out the form for it, I use check_date:currency:XBT to indicate that the site accepts Bitcoin as a payment method on the day of its verification.

I want to mention that all the places I have added to the map are checked and re-checked; nothing is added lightly. 
There is a prior verification, whether by email, the business's website, or calling the person directly.

If a site does not have a physical location on the map, I explain to the owner that it cannot be added because it violates OSM rules.

 I hope you understand how things work in BTC Map. 

If you have any other questions, please write on Discord.

Thank you very much, and have a great day.
