The one way to buy it is in Indonesia. Bitcoin.co.id
But it's 20% more expensive there.
Anywhere else?
We are located at Indonesia, Singapore, US.
(by fiat of course, otherwise there are tons of options)
I am glad that finally Indonesia have its own bitcoin exchanger wherein they can exchange their fiat currency to bitcoin and vice versa. In our country Philippines we also have that kind of btc exchange and it is called coins.ph. It is really very convenient to avail of bitcoin using our local currency thus I say I am happy for the bitcoin community in Indonesia.
