If the government regulates the existence of legal crypto and crypto in a country, of course this will have an impact on crypto such as strict supervision and taxation by that country. This also has a great influence on its users, both from a positive and a negative side. On the plus side, all of our assets are safely protected, if you look at the downside, huge taxes will be incurred in crypto trading.
I'm not sure if our assets will be safely protected if the government regulates crypto use. It depends on what government regulates for example many countries only regulate bitcoin use and some cryptocurrencies most of them didn't regulate NFT, metaverse, IPO, etc. The potential from it making crypto vulnerable to money laundering. Most countries only want our money by implementing tax by using bitcoin or other coins.
