Bitcoin is one of the most successful open source projects to have ever been created, and it gets downvoted to hell anywhere it gets brought up. 15 years of growth in network size, usage, and capability. Surviving attacks and attempted bans from nation-states. Not a single hour of downtime, not a single hack, reliably transferring money across the globe to anybody with a cell phone and a halfway reliable internet connection in seconds to minutes for pennies to dollars in fees. 100% open source and decentralized, uncorruptible, open to whoever wants to use it, the way currency should be. It's got a market cap bigger than Sweden's GDP and is already more reliable and widely accepted than most national currencies. Nobody can make it print money it isn't meant to print or move money it isn't supposed to move.
