In my country (Indonesia), Bank Indonesia is starting with the transaction services. The central bank wants to ban any tech company, e-commerce site, or payment system that accepts Bitcoin as a valid payment in Indonesia. That means you can't use your Bitcoin wallet to buy a pizza or purchase airline tickets in Indonesia.
The concern here is that Bitcoin could be used for money laundering or terrorism, according to central bank officials. They were also concerned that Bitcoin could destabilize the Rupiahone of the most-volatile currencies in Southeast Asia.
Central bank Indonesia only ban bitcoin as payment but if we have bitcoin and hold it as investment, Indonesia government allowed. I am believe that bitcoin can make economy and investment weather more attractive if bitcoin have regulation
