Has anyone studied the legality of mining taxes? In which countries can you officially mine, pay taxes and sleep peacefully?
Just look at which countries have fully legalized cryptocurrency. As of today, cryptocurrency is fully legalized in 15 countries. These are Belarus, Canada, Germany, Canada, El Salvador, Germany, Italy, Malta, Norway, Spain, El Salvador, USA, Ukraine, Philippines, Spain, Czech Republic, Switzerland, Estonia, Japan. And if cryptocurrency is fully legalized, it means that cryptocurrency mining is also allowed. Please, pay taxes and do mining for health

I think so.
