More important phrases for introducing cryptocurrencies in my opinion:

• Instead of the government and banks creating money, in cryptocurrencies the money is created by a network that ensures inflation is low.

• You can make direct payments like cash, no 3rd party tools like Paypal are required.

• Keep your private keys safe and always have at least one backup.

• Do not trust any service that promises interest, and always double-check the address before sending money. Transactions are not reversible.
