I don't like the fact that bitcoins is taking the role of a central Altcoin authority "since it should all be about decentralization" but it only makes sense IMO, Altcoins are not well established and with high demand like BTC is "and hence having direct USD/Fiat to BTC channels" therefore Altcoins can only value itself on BTC value.
Some altcoins have broken from this though, from example ETH, that not only exchanged with USD through exchanges, but can also be directly bought with USD and other currencies.

indeed, now in 2017 this is even more apparent now, bitcoin is actually taking the form of the international boarder-less country. there are exchanges right now for every single part of the world from Africa to South America and Australia, meaning BTC is not just US/EU based like it used to be. Even China and Eastern Asia have been the spine of BTC now.

Teenagers shouldn't be hard to explain to, if they have interest in these kinds of things though (The same for adults, you wouldn't get anything if they have no interest in technology or payment systems)
Children would be difficult to explain to if they are particularly young IMO.
