"Foreign tourists who behave inappropriately, carry out activities that are not allowed in their visa permit, use crypto as a means of payment, and violate other provisions will be dealt with firmly," Bali Governor Wayan Koster said at a press conference on May 28, as cited by Antara news agency.
He reminded tourists that Indonesia’s law prohibits the use of currencies other than the rupiah as a means of payment, with punishments including a jail term of up to a year and a fine of 200 million rupiah (US$13,360).
The warning came after Indonesian authorities found that a number of businesses including restaurants, meditation studios, and motorbike rental companies are accepting payment in crypto.
Famous for its beaches and ancient temples, Bali has become a top tourist destination in recent years thanks to its generous visa policies.
It has been cracking down on foreigners violating public order following a recent string of untoward incidents.
Immigration authorities have deported almost 125 people in the first five months of this year, most of them for overstaying their visa.
