Too Long; Didn't Read
Bitcoin is just superior: it’s decentralized, it’s not controlled by any nefarious central entity, its supply curve is very predictable, and so on. Bitcoin will make the existing financial system obsolete, and it (the system) will transform itself to adapt to crypto. It’s programmed. I do agree that Bitcoin’s code is a work of genius and possibly one of the most important innovations of the 21st century, like the creation of the World Wide Web by Tim Berners-Lee in 1989. But in and of itself it’s not enough to make BTC the universal currency, because decentralization and supply predictability isn’t what most people value most.
You have to think of regular consumers in different regions of the world and what they want from money in their everyday life. Low transaction cost, speed, stable value, universal acceptance – all the things that Bitcoin doesn’t have. Cryptos like XLM or XRP are perhaps closer to the ideal, but acceptance will remain a huge problem for many years. Being decentralized and fair isn’t enough: digital money needs to become as easy to use on the day-to-day level as fiat, and right now it’s just not the case.
