Governments see Bitcoin as a threat to their control over the financial system. While fiat currencies, such as the dollar and the real, are controlled and tracked, Bitcoin is decentralized, allowing financial freedom without intermediaries. This is a political concern, which may soon limit or even prevent the purchase of Bitcoin with state currency. In the future, obtaining Bitcoin may become extremely difficult, requiring effort, sacrifices and extreme alternatives such as mining or direct negotiations. The fight for financial freedom through Bitcoin will be increasingly challenging.
