Mark Karpelès
The world’s largest bitcoin exchange pumps up the price of BTC well above competing exchanges, stops allowing cash withdrawals, blocks bitcoin withdrawals, and finally comes crashing down claiming that they were hacked. All of this from an ex-pat CEO living in Japan who was convicted of crimes in his home country in absentia. Hundreds of millions of dollars went missing and all blockchain analysis points to Mr. Karpelès either being the dumbest developer in the history of mankind or complicit in the theft of Mt. Gox user’s funds.
