2. Crypto is the future of money
Accept it or not, cryptocurrencies are the future of money and payments. With the world going digital and using the internet/mobile for performing even small to small everyday tasks, it is only inevitable that everyone around the world starts using digital money for payment-related transactions.
You should add a remark, that it is future, in future with the Internet everyone:) There are still areas in the World without it. Or a place were internet is limited.
Easy example - cruise ships. Either you buy a costly internet package with low speed, or you are without "future money" when ship is at sea. And there are lots of other examples.
