Is it legal to use bitcoin in a domain name? Not a sub domain, but in the main domain name.

  • What do you mean 'in' a domain name? A domain name which contains the substring 'bitcoin'? Buying a domain name with bitcoin? Putting a bitcoin address on a website? Jan 27, 2013 at 21:08
  • @PieterWuille like bitcoinShop.com so the main domain name has the word bitcoin in it not a subdomain like bitcoin.example.com

    @PieterWuille just wanted to make sure cause its based on MIT license and opensource but the name it self might be registered for some reason. Thanks for your help Pieter :))

To date, no entity has trademarked word "Bitcoin" in the US. This means that it's highly unlikely that any US entity would file against your domains under the ICANN Uniform Domain-Name Dispute-Resolution Policy.

There was a servicemark application for Bitcoin, but it was abandoned in July 2011.
