I see so many people wearing signatures these days.
How do you state the cryptocurrency income from signature campaigns in your tax return? The tax authorities in Europe want to provide them with a document for the purchase of cryptocurrency, I guess it's the same for USA & Canada with the AML laws.
In countries that crypto is illegal, they don't care whether you got your crypto earning from signature campaigns or not. Any crypto assets in your portfolio are illegal to them. You must omit it from their reach to avoid being jailed for it
