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 ?
Bitcoin is just a cryptocurrency so it cannot be considered to be dangerous. The dangerous thing here in bitcoin is the way we earn bitcoin. There are a lot of scammers and frauds here so it will be dangerous if you are going to be careless here. Many people are already failing here because of being too careless so you better be aware and mindful on what's happening in the market.
