Prince al-Waleed bin Talal once called bitcoin an “Enron in the making.” Two months later, the Saudi royal suddenly finds himself looking up at the man or woman (or group) behind the soaring cryptocurrency on the list of the world’s wealthiest billionaires, according to numbers crunched by Quartz on Monday.

And yet, even after all the buzz, we still don’t know who the bitcoin’s anonymous creator, known as “Satoshi Nakamoto,” actually is. Perhaps an Australian entrepreneur? No. Or maybe it’s Tesla’s TSLA, -10.34% Elon Musk? Guess again.
