Do you know if there is any shop out there that has Bitcoin merchandising or Alts stuff? I assume that many of the logos are registered brands, but not so sure about BTC.
I know a lot of T-shirts have been sold already with Bitcoin and other altcoin's logo with it, so not sure about the registered brands and all of that stuff.
Go to the big G, for sure you will see merchandise shops offering it.
And if I'm not mistaken, Bitcoin (
BTC) logo is free to use:
