We can’t really predict on the future of cryptocurrencies, but I can tell you that cryptocurrency is heading to a bigger step with its present situation and crypto is circulating all over the world. Most people are using crypto, and there day to day payments, even the small business owners, so therefore, if cryptocurrency continue with this for the next 20 years at least I can predict that it will take over 60% of the currency exchange around the globe But I can say this that cryptocurrency will only be used as exchange of commodity, or between our countries, and even in different individual countries, but it will never crash a Local currency, but it will be used as exchange between two countries doing some transactions.
