Fiat is manipulated by governments/banks to control & have power. Whales heavily manipulate crypto. By switching to crypto, isn't it just handing the control & power from governments/banks to a small group of wealthy whales?
Let's think more openly and read more about economics. The government "manipulates" national finance for the stability of the country's economy, it is for your welfare as citizens, so please stop saying things that are not quite right as if the government is "using power" only. The crypto market is also not completely controlled by whales, ah this is quite complicated but big waves can form from the accumulation of small waves, right?
Cryptocurrency and national currency both have advantages, we should use both of them well to get the maximum profit. National currency with legal laws, a cryptocurrency with high-value investment and trade opportunities. So, just take advantage of both without having to get rid of one of them.
