I don't think that governments will ever prohibit new cryptocurrencies from being developed. I don't see cryptocurrencies as a threat for fiat currencies. They have completely different systems and their goals are also different for people. Rather than these cryptocurrencies, the biggest threat for fiat currencies will be the digital currencies which are developed by governments. Because in the future, they will start replacing fiat currencies one by one.
- Well, asmall peninsula like crypto can't yet threaten large swathes of land like government and fiat but if we want to go with the natural, ignoring the development of crypto is impossible for the government because the minerals in this small peninsula are mined by many people and this behavior is not safe, people here sometimes bring some pain and spread to others in the community. The developer is a place to experiment and create new minerals, the experiment will have consequences on users is what the government is worried about
