But I don’t think for a second that cryptocurrencies will ever replace gold, for a number of reasons. For one, cryptos are strictly forms of currency, whereas gold has many other time-tested applications, from jewelry to dentistry to electronics.

Unlike cryptos, gold doesn’t require electricity to trade. This makes it especially useful in situations such as hurricane-ravished Puerto Rico, where 95 percent of people are reportedly still without power. Right now the island’s economy is cash-only. If you have gold jewelry or coins, they can be converted into cash—all without electricity or WiFi.

Finally, gold remains one of the most liquid assets, traded daily in well-established exchanges all around the globe. Every day, some £13.8 billion, or $18 billion, worth of physical gold are traded in London alone, according to the London Bullion Market Association (LBMA). The cryptocurrency market, although expanding rapidly, is not quite there yet.

I will admit, though, that bitcoin is energizing some investors, especially millennials, in ways that gold might have a hard time doing. The proof is all over the internet. You can find a number of TED Talks on bitcoin, cryptocurrencies and the blockchain, but to my knowledge, none is available on gold investing. YouTube is likewise bursting at the seams with videos on cryptos.

Bitcoin is up 350 percent for the year, Ethereum an unbelievable 3,600 percent. Gold, meanwhile, is up around 10 percent. Producers, as measured by the NYSE Arca Gold Miners Index, have gained 11.5 percent in 2017, 23 percent since its 52-week low in December 2016.
