I'm interested in trading cryptocurrency domain names but I'm confused about the words "bitcoin" / "btc" if they are trademark-protected?? "BITCOIN itself is registered as an EU trade mark in the name of bitFlyer Inc., a Japanese company" that's according to the U.K. chartered institute of the trademark attorneys https://www.citma.org.uk/resources/...her-cryptocurrency-brands-trademark-blog.html also says "The picture with regard to trade mark ownership of the word BITCOIN for the core “financial services” is therefore unclear, although in the US, a UK company called Coin Legal Ltd claims to have used the mark BITCOIN since January 2009. The UK and EU trade mark registers appear to show that trade mark applications in the name of various different entities are being accepted for trade marks that cover “financial services” and include the word BITCOIN, as long as it is featured with another distinctive word or brand name. " This information is from 2019. Is there anything concrete from 2021 and that covers the UNITED STATES and other countries for domain name registrations of "bitcoin" and "btc"?
