If you really want to "copyright" tickers in an open source land, your only foundation for doing so is to get listed on exchanges, so you can have a URL that is in a third party system to verify your ticker, such as:
https://c-cex.com/?p=bti-btcNotice, we didn't create this URL, but it's the BTI symbol and it's referencing a cryptocurrency that functions under the umbrella that is Blockchain Technologies Inc. If there was a such thing as "copyright" in these parts, we beat you to it.
If you really want to criticize our due diligence, put yourselves in our shoes. We come across a "coin" named BTI, that has a couple pools, but no website, no exchanges have it listed, the source hasn't been updated in almost a year, and seems no one has even commented in the thread since last year either.
We ignored you, as you ignored your own creation. Your coin is dead in the water man, and it's your own fault.
Keep up the comments though! I'll be right here waiting for more
