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?
A lot of countries of governments don't have any clear law that prohibits nor allows the use of cryptocurrency or bitcoin, but a they will use other laws or reasons if you are found to be using them for illegal purposes or making a lot of money from them and not paying taxes, for example in my country i guy went for jail because he was buying and selling bitcoin and he was trialed under the law of the use of foreign currency which is not allowed.
