Crypto's Double-Edged Sword: Volatility and Tax Evasion

Nobel laureate Paul Krugman was not a fan of cryptocurrencies back in 2019. He saw their future as dim. But even he couldn't deny that cryptocurrencies are big players today. They've changed how we think about money and finance. Governments are watching closely, trying to keep up with these digital coins. One big worry is how much energy cryptocurrencies use. They need a lot of power to run, which isn't good for the environment. Plus, many people use cryptocurrencies to hide their money, making it easier to cheat on taxes. And when it comes to environmental taxes, this can be a real problem. The paper has two main goals. First, it wants to show that cryptocurrencies are risky because they're so volatile. They can go up and down in value really fast. Second, it wants to talk about how cryptocurrencies can be used to dodge taxes. This is a big deal because money from green taxes could be used for important projects. So, what should be done? The paper says we need clear rules worldwide to stop people from using cryptocurrencies to avoid taxes. That way, we can make sure we're taking care of our environment properly.
