Is it just trading or possession? I mean what if someone sells a product and gets crypto in return?
It's an income tax and it's for when one sells crypto for money.
It doesn't matter you bought one Bitcoin for 20000$ or for 1$, if you sell it they want 10% of the money you received (preev tells now 3438$) as tax.
I don't expect many individuals will do this; it's just one more of the stupid laws my country started to get in the last 2 years at an accelerated rate.
I read it differently. It says in the article that
Only incomes or profits are taxed
Which means that you'd only get taxed if you do make a profit on your bitcoin in comparison to when you bought it initially.
If you do make a loss then it won't count as taxable, from what I can gather from the article above. In certain countries you might even be able to claim that as a deduction, but not sure about Romania.
That isn't actually too bad compared to a lot of countries worldwide where CGT is a lot higher. Though, I'm not sure if Romania will have special rules in regards to the use of bitcoin as a currency to buy goods (i.e. if you use bitcoins you bought a while back to buy something online when bitcoin has risen, will that also be taxable?) or not.
