A: "Cryptocurrency" should be plural because there are many different types of cryptocurrencies, for example: Bitcoin, Litecoin, Ethereum, etc. So a more accurate way to say this would be, "Cryptocurrencies can change the world".

If you want to be specific or keep cryptocurrency singular, I would recommend using a specific cryptocurrency as your subject and then link it with cryptocurrency, for example: "Bitcoin is a cryptocurrency that can change the world".
