I'm wondering why bitcoin was made if there are too many currencies in each country, why would anyone add or make a type of currency in the internet? For easier and faster transactions or so ?
Well bitcoin was made so that people has its own freedom to hold their own money without the banks monitoring them, to just simplify it

it is decentralized, its kinda fast in transaction and you can't fake it or spend it twice so people can't cheat you when sending bitcoin

Paper money in the future wil have no value, it will all be digital.
