Copyright in cryptocurrency is a complex topic, many crypto currencies are created by a corporate entity others by individuals. In some depending in some cases when the currency was created the associated logo was releasesd under a commercial licence requiring permission to use it, despite the fact the use of the logo may be “free marketing” for the copyright holder.
I’m going to collect together a list of logos and evidence of what licence they are released under in this post, hope it is of use to someone.
|Source of Logo
|Unknown - the file in Wikimedia Commons is marked as public domain due a simple composition of geometric shapes, however the logo is likely part of Binance’s wider trademarks.
|Public Domain - the original log was releaed as public domain, although it should be noted that at least one person has registered the logo and symbol as trademarked to “protect it from misuse”.
|Public Domain - see above.
|Polkadot Brand Assets

|Stellar Press Kit
