Does every crypto have a white paper?
Hello there, I'm curious about the world of cryptocurrency and I've noticed that many projects seem to have a document called a 'white paper.' My question is, does every crypto project out there have a white paper? Is it a requirement or is it more of a best practice? I understand that a white paper outlines the project's vision, goals, and technical details, but I'm wondering if there are any exceptions to this rule. Could you shed some light on this matter?
Who is on every US coin?
I'm curious, who exactly is featured on every US coin? Are there any specific historical figures or symbols that consistently appear across different denominations? Is there a standard design that all US coins adhere to, or does it vary depending on the coin's value or year of minting? I'm interested in learning more about the symbolism and history behind the faces and images that grace our nation's currency.
