I don't agree with you. Bitcoin was born in the financial crisis. It avoids inflation and is conducive to economic stability.
It simplifies the currency exchange between countries and does not need complicated steps.
Even if there is no bitcoin, there will be another kind of currency to achieve this function.
There can be no currency which can replace bitcoin at the moment. All other altcoins are somewhat centralized and no one is pure decentralized as bitcoin. Governments may argue that bitcoin is not good for the econmony because if bitcoin is adopted gov. will lose control over the financial systems.
