Craig Steven Wright, an Australian, is the latest in a line of men alleged to be the mysterious creator of bitcoin, a digital currency that has attracted the interest of banks, speculators, criminals and regulators.
Wired magazine, which along with fellow U.S. publication Gizmodo published a story outing Wright based on a stash of leaked documents and emails, called him a genius.
But interviews with those who have done business with Wright, and a closer inspection of documents published by the two technology websites, paint a more complex picture.
