Can I use Bitcoin to send money from a US bank to an Indonesian bank? I now live in Indonesia and want to send money from my US bank account to an Indonesian bank. Can I use Bitcoin to do this transfer?
Bitcoin is not well integrated with the legacy banking system. What you want to do would therefore go somewhat like this:


Open an account with a Bitcoin exchange (A) that takes US customers. (Assuming you are a US citizen.)
Deposit USD into the Bitcoin exchange.
Open an account with a Bitcoin exchange (B) that serves the Indonesian market.
Buy bitcoins for USD on A, transfer the bitcoins to B, sell the bitcoins for Indonesian Rupiah on B
Withdraw Indonesian Rupiah from B to your bank account in Indonesia.


As you can see this is somewhat complicated, and there are likely ways to make this transfer more easily. However, I have successfully used a similar method to transfer money to myself in the past and it was much cheaper than an international wire transfer.
