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.
Great points!
