This era of teenagers and children, I guess can easily adapt to changes. Due to advance technology, they already have access to the web. Which I think gives a leverage in the future. I do agree in a sense that BTC could be the future money and BTC is really hard to explain. Though we could only assist them in understanding things, We can't provide everything to these kids. But, If ever bitcoin would be accepted as money worldwide. For sure that every schools and colleges would do add cryptocurrencies as part of the curriculum.
