A few days ago, it was learned that El Salvador has set Bitcoin as legal tender, China has banned mining, and India has also stated that it has banned cryptocurrency by legislation. Recently, the German Fund Positioning Act allows investment in cryptocurrency, but in the past few days, I have seen a lot of discussions about whether Bitcoin is legal. What should I do if Bitcoin is prohibited in my country/region? If mining is prohibited, do I need to switch to a place that recognizes Bitcoin to continue mining?
