I learned from the study conducted by the chainalysis that Five million bitcoins (one third of available supply) is controlled by the 1,000 largest long term investors, 7.4 million in total long-term investment. It is also known that at least 2.3 million bitcoins have been lost. The remaining 7.3 million available are used for speculation and transactions by services, such as exchanges, 4 million are not yet mined.
Here are the six largest bitcoin holders:1. Satoshi Nakamoto - 1 000 000 bitcoins, which are still untouchable.

Corrected by Kakmakr : Roger Ver said he sold most of his coins3. Mt.Gox - 166 000 bitcoins, 34 000 of them were recently sold collapsing the market severely.

Tyler and Cameron Winklevoss - brothers who owned the idea of Facebook creation, they bought Bitcoins for 11$ million in 2013, when the price was $ 120 per coin.
