I'm surprised by the way you say that cryptocurrencies and mathematical records are useless and just waste energy and time.

Have you considered the possibility that these technologies have many applications in the modern world? Have you ever considered that they could be an important tool to protect users' digital rights and ensure transparency and integrity of records? Before you say stupid things, do your research.

... You've certainly given me food for thought. The way you've described it, one could argue that cryptocurrency lacks the fundamental trait that defines an asset. There's no tangible use or financial benefit to it, besides the abstract belief that its value will rise in the future.

Yet it still works, somehow. People still... put value into it.
