I view cryptocurrency and gold as almost one and the same. The technology behind these digital currencies make it function like gold in a lot of ways. What made gold valuable as money? It was highly "saleable", rare, divisible, and has uses outside of being a medium of exchange.

Cryptocurrencies simulate the saleableness, rarity, and ease of division digitally and I would argue that like gold, have a secondary use outside of a medium of exchange as a great payment system.

I think the two will only really strengthen each other and highlight the terribleness of fiat currencies foisted upon us by governments.
