Bitcoin started as an obscure digital experiment and has grown into a global asset that governments cannot ignore. This DW film by Tom Ockers and Ulrich Stein tracks how far that shift has gone, from El Salvador's decision to make Bitcoin legal tender to the European Central Bank's public bets on the currency's collapse while it simultaneously develops a digital euro for smartphone payments. Interviews mix people who made money on the crypto wave with people who lost it, alongside economists and central bankers who see the technology as either dangerous speculation or the necessary future of payments. The film does not settle the argument; instead it lays out the mechanics of how crypto has already forced regulators and institutions to react, whether through outright bans, cautious adoption, or state-backed digital currencies designed to compete with it. The result is a grounded look at a technology still being fought over by the people it was built to bypass.
