Wouldn't it be the same as what the tax authorities expect of street buskers, where something was done publicly (just here on the internet) and as a result randoms gave you money/cash (here again the digital equivalent) after the fact with no strings attached?

Yes, just the auditor looked like she was ready to call in the police for fraud when I said it.
Also, I live in a place where that was probably many months pay to the auditor.
Made my tax audit rather painful.... "I posted a joke on the internet about binary numbers not being worth anything and someone gave me $10k of bitcoin that I'm now declaring - is it income for the work of writing the joke, or a gift? The sender likely didn't know who I was, and was likely overseas but I cannot prove who they were or which country they were in".
