In Ukraine everything is indefinite. You can buy a house paid by Etherium, but you can't simply buy cryptocurrency using your banking account.
Then the direct purchase is not allowed, but the indirect, as you quoted one can buy a house. Well, here in Brazil, it's all good.
Here in my place, you can use cryptocurrency only to those businesses who accepts cryptocurrency as mode of payment but overall cryptocurrency is doing well here because we can still trade it and convert it into fiat money through our local wallet. There is no final regulations about cryptocurrency but I still hope for a positive things so we freely enjoy this kind of technology.
