Bitcoin is an innovative payment network and a new kind of money. Bitcoin uses peer-to-peer technology to operate with no central authority or banks managing transactions and the issuing of bitcoins is carried out collectively by the network.

For example, you can install an app on your mobile device for everyday use or you can have a wallet only for online payments on your computer.

In any case, choosing a wallet is easy and can be done in minutes. You can get Bitcoin by accepting it as a payment for goods and services.

There are also several ways you can buy Bitcoin. There are a growing number of services and merchants accepting Bitcoin all over the world.

However, Bitcoin is different than what you know and use every day. You can process payments and invoices by yourself or you can use merchant services and deposit money in your local currency or bitcoins.

Most point of sales businesses use a tablet or a mobile phone to let customers pay with their mobile phones. Merchants often deposit and display prices in their local currency.
