Any royalty payments for using Bitcoin logo in an NFT

I am creating my first set of NFT artwork/cards. I want to add in the Bitcoin and other currencies logos into my artwork. Do I have to pay royalties, show copyright claims, or any other financial/legal issues before I sell?

I congratulate you. I am very glad to hear that you are doing something like this because I am the kind of artist who creates logos. The subject of Bitcoin is not very close to me, so I can hardly give you an exact answer to your question, but I am sure that you need to ask more knowledgeable people for advice because it is more serious. As for the logo, I’d be interested to know where you get your ideas from. I for example started with different logo design sites like where you can create your own Design. My theme is artistic. I’ve already even worked with an art gallery Maybe you may also be interested in it.
