The taxation system implemented by governments often covers expenses not authorized by society, such as military or migration costs. Cryptocurrencies offer transparency and autonomy. The tax system could record income through blockchain, automatically applying taxes without interfering with each transaction. This would eliminate conflicts with regulators and ensure financial freedom. The outdated banking system, based on control, is inferior to blockchain, which offers a transparent and notifying approach. It is time for governments to create systems that respect citizens' rights and their freedom to manage their funds.
