TEMPO.CO, Jakarta - Bank Indonesia (BI) has banned the use of Bitcoins in financial transactions. The central bank said that transactions using the virtual currency are against the law because the only valid instrument for payment in Indonesia is the rupiah.
BI executive director of payment system policy and supervision Eny V. Panggabean said Eny said the ban was issued to protect the people. The use of bitcoin is considered risky because it does not have a liable institution.
BI also said that Bitcoins have the potential to be used for criminal activities such as drug dealings or credit card purchases using other people's cards.
