Bitcoin`s rising price attracting more and more investors all over the world. These investors are pulling money from their traditional investments and investing it in bitcoin currency. Similarly they stopped using fiat currency in their day to day life. As a result circulation of fiat currency get disturbed so as the economy. As a result Indonesia and other countries banned bitcoin currency completely from their economy by giving security and stability reasons. In future many more countries can ban or regulate bitcoin currency.
How could people have stopped using fiat on their daily life if there are only about 100.000 businesses in the world accepting Bitcoin as payment? We can't live without fiat. Bitcoin boosts countries economies a lot when people convert their Bitcoin profit to fiat. You are putting money in circulation in your country, the government should feel proud of their people and not ban Bitcoins.
Bitcoin is unstable and doesn't guarantee any stability for your country, if using it as store of value, but on the individual life it has only advantages.
