“A coder and independent security researcher named Sergio Lerner conducted a detailed analysis of the block chain at the time Satoshi was still mining. He concluded that Satoshi had mined at least one million bitcoins – more precisely 1,148,800. Lerner felt that if any of these coins had been spent, it would not be difficult to work out Satoshi’s identity – the recipient of the coins would know, unless the sender had sent the coins anonymously. But it appears that none of them were ever spent.”
