Mining is the extraction (removal) of minerals and metals from earth. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds are just some examples of what is mined.
Mining bitcoin ,not mining of minerals and whatsoever it is. Mining is available in every country, you can mine directly on your pc or you can join on cloud mining site. But for me mining is not profitable these days.
