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?
In my country there is no prohibition to trade in crypto. However, the government has announced that bitcoin is not legal tender in our country. So it doesn't matter to us because there are no restrictions. Only not valid in transactions as a means of payment.
