Some countries banned crypto assets totally, some banned mining, some allows even paying taxes with it and some doesn't allow purchasing goods using crypto assets.
The Republic of Turkey has a strict ban against using crypto assets as a way of payment or developing technological infrastructure for such use case. However, it is perfectly legal for individuals and businesses to buy/sell/mine/trade the crypto assets.
What is the situation in other countries that you know of? And do you think the world will start accepting it or will regulate and see it only as a "store of value" and not a currency?
Previously in my country, Trading bitcoin was no problem until there was this international publication that ranked countries with regards to Bitcoin investment, and my country was ranked among the top 5 with the total estimation of investment then the Government decided to Ban the transaction of cryptocurrencies by every other financial institution in the country. Bitcoin and other cryptos are still been traded though but only via P2P and it will take a very long time IMO for Bitcoin to be globally accepted as a full-fledged currency and I believe even then, there will be some strict regulations.
