The Government of most countries are still seeing Bitcoin as a tool that can distort the economy's economic activities of the society just because it is Deregulated and at the same Decentralized. Hence, it is given rooms to Criminalities where indigents or the country's residents are being scammed uncontrollably or uncheckably. The Governments wants to fully support what they have full control over.
I think that's why the government is tense about it because it can hamper the normal tendency to control a country from all sides. This is really a matter of worry because crypto has systematic and structural problems. So the government can not accept this.
Cryptocurrency is the most frequent existence as for those who want an easy way of living, smart trading, investing in oral bills and paying without permanent documents.
