Cryptocurrency is not tied to any rules or regulations of any specific government, exchange rates, interest rates and country to country transaction fees. International transactions will move faster.
Using Cryptocurrency not only protects your identity but also allows those accepting it to protect from fraud as well. There are no chargebacks to worry about either, which is a big reason so many are turning away from accepting credit cards.
By accepting Cryptocurrency on your website you engage a wider audience that can only increase your profits.
