Even though most of the people buying Ether and Bitcoin are individual investors, the gains that both have experienced have taken what was until very recently a quirky fringe experiment into the realm of big money. The combined value of all Ether and Bitcoin is now worth more than the market value of PayPal and is approaching the size of Goldman Sachs.

Bitcoin, on the other hand, has made inroads into mainstream commerce, with companies like Overstock.com and Expedia accepting Bitcoin for purchases, along with the black-market operators who use the currency.

Mr. Buterin was inspired by Bitcoin, and the software he built shares some of the same basic qualities. Both are hosted and maintained by the computers of volunteers around the world, who are rewarded for their participation with the new digital tokens that are released onto the network each day.
Because the virtual currencies are tracked and maintained by a network of computers, no government or company is in charge. The prices of both…
