Not many legal ones, yet, anyway. I'm always struck by how there is basically no mention of bittorrent in conversations about web3. It was web3 (decentralized, cryptography-based) technology that's about 20 years old. And at first the notion was that people would save on server/bandwidth costs by sharing server/bandwidth for large files. But we still have "Moore's Law" or something like it for Internet connectivity and storage space so it ended up being almost exclusively used for piracy. This is more or less exactly what is going on with bitcoin. Right now, people are using it here and there for transactions, but not out of necessity really. There are a few cases in certain countries, as pointed out by people like Garry Kasparov, that being able to avoid the authorities is a good thing. But in general, it's an academic argument because the authorities will do what they need to do. And for a long time, bitcoin was just bittorrent for money. Mostly used for illegal stuff like SilkRoad. So, while there are a few limited use cases now and may be a lot in the future, "trust me bro, it's gonna rule!" isn't good enough for me to put faith or money into.
