Best performing asset in the history of mankind. Removes counterparty risk. Removes middlemen. Privacy (if you work for it.) Better uptime than your bank and credit card network. Is a better way to login to things, self sovereign usernames and passwords, which are easy to use across all platforms (if they would stop with the lock-in.) The most transparent trading in the world. The highest yields in the world for those that want to just provide liquidity and have less risk.
A platform for things I don't like, but others love, customer rewards programs, collectibles, proof of ownership, timestamping. Removing the government money printing press from free war funding, and perhaps requiring a war tax, would reduce military globally. An impossible to fake record of the past, if you pay to write to the db.
You can get loans 24 hours a day with no signup that allow you to pay less tax by not selling the asset and paying capital gains, and just living off the borrowed money (like the wealthy have been doing for decades.) Shall I continue, or will you be ignoring all these features and benefits anyway?
