Satoshi is estimated to have mined more than 22,000 blocks since Bitcoin's inception in 2009, receiving more than a million bitcoins as a reward. He currently holds more than 1.1 million BTC, distributed across around 22,000 different addresses. These bitcoins have not been spent since Satoshi left the project in 2010.
In addition to Satoshi, other significant bitcoin holders include the Winklevoss twins, who acquired around 70,000 BTC following a deal with Mark Zuckerberg.
