There’s no uniform policy to taxing cryptocurrencies. Some nations have taken a more liberal approach than others.
Tax liability is a major source of concern for anyone invested in Bitcoin and other digital assets. In sum, some have described it as nothing short of a nightmare.
But while some countries are putting pressure on investors and levying taxes on income and capital gains from Bitcoin transactions, many are taking a different approach—often with the aim of promoting better adoption and innovation within the crypto industry. They’ve implemented friendlier legislation, and allow investors to buy, sell, or hold digital assets with no tax liability.
