What use cases have you found in crypto outside of making money

When the people behind XRP addressed this question as part of their legal case against the SEC a while ago, it became abundantly clear that cryptocurrencies have a wide variety of applications, and this was one of the most important takeaways from the discussion. But I will question it here: what use cases have you seen with cryptocurrency that are outside of the regular buying, selling, gambling, and moving money to someone else?

​

Do you ever make use of any of the scenarios that you describe? How does it assist you?

​

Some use cases I seen is supply chain tracking, smart contracts, and a few other things.
