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 ?
I don't think that it is dangerous. I think that bitcoins would be dangerous if we use it illegally, for example we use bitcoins in a campaign or any job that we announced and you are going to reward them for the job they did, but instead you just keep it and you don't pay your workers, then it could be a source of your danger coming from the people you tricked to.
