Hey beatnickgr, thanks for this comment. 

With btcmap.org we were trying to verify over 7000 merchants on OSM with legacy tags. I always first tried to find any trace of bitcoin on their websites, If there's not, contact them by email/facebook/twitter/instagram.

Since the task was enormous and after a short while we realised 90% of those places do not accept anymore, I decided to delete them first and then If I get a confirmation that they do, bring back the tag. 

Most of the time merchants didn't answer the messages sent, and If they did, it was usually negative. I can't tell you now which method it was with the three merchants you tagged, but I always tried to do this.

This method is not perfect and was susceptible to mistakes, which this clearly is, as crypto is mentioned on their website. I am sorry to delete your work here. I will happily revert those back If you want. I definately do not want merchans that accept bitcoin do not be on OSM and btcmap.org 

But the good thing now is that all of the new tags pretty much well verified, with very little room for mistakes. So before we had over 7k places with bitcoin payments, from which maybe maximum 10% really accepted bitcoin. Now we have about 10k places tagged and I am sure more than 95% of those are truly accepting it 

At btcmap.org there's a push for local communities to really maintain and verify their local merchants (see https://btcmap.org/communities/map#2/5.26601/0.17578), so this kind of mistakes are getting minmalised I think 

Once again sorry and let me know If you want to tag them again or should I do it
