A community without taxes and applied in the country I can not. Taxes are revenue for the government so that taxes cannot be removed. Earnings from Bitcoin indeed in my country have not been exposed to government taxes. But if later the government can legalize Bitcoin, I think the income from Bitcoin will be taxable.

Life if there is no tax like dreaming and living without tax it can only be done in a rich country. Because everybody has a life assurance from the government.
