Bitcoin can be used to transact the same as the US dollar and rupiah, but Bitcoin is in virtual form, and currently services that accept Bitcoin use are still small.

How can Bitcoin be used? Basically, people who own Bitcoin will give digital money to Bitcoin, just like a bank that has a journal to collect its customers, but digital journal Bitcoin is not owned by any institution.

In Bitcoin, digital journals can be seen by Bitcoin owners. If the digital journal is damaged the digital journal owners still have their reserves from other Bitcoin owners and no one controls them because everything helps them.
