"Still, based on our speculations and the data released by people, here are some of the people who hold a big chunk of Bitcoins
Satoshi Nakamoto: The mind behind Bitcoin, it is believed to have a total of 1,148,800 unspent coins spread across various addresses. That’s about 63% unspent coins. It’s tough to determine all addresses which belong to him. We do know some from the fact that genesis block and some of the earlier blocks were mined by him. People still send contributions to those.
Hal Finney: Hal Finey (died in 2014) was the first person to receive Bitcoin in a transaction. Satoshi sent 10 BTC to him as a test. He even did some mining.
The Winklevoss twins: Cameron Winklevoss and Tyler Winklevoss, claim to have around 1% of the total Bitcoins in existence. They announced in April 2013 that they had acquired $11 million worth of Bitcoins.
Tim Draper: When Silkroad shut down, FBI seized its funds. It got access to a wallet having 144,000 BTC and another having 30,000 BTC. The money was auctioned off in batches. This is when Tim Draper entered the club of top holders. He was the single winning bidder for nearly 30,000 BTC.
Ross Ulbricht: He is allegedly the administrator of Silk Road going by the pseudonym “Dread Pirate Roberts”. Silk road generated around 615,000 BTC from things like transaction fees. Not all of the money was seized by FBI, and it still unclear how much of the revenue, Ross might have used.
Mark Karpeles: It is also assumed that Mt Gox Exchange founder, Mark Karpeles holds a good amount of BTC. However, we can’t say much.
That being said, one thing we can know for sure is how much Bitcoins a particular address holds. Here is a list of top 100 addresses with the most number of Bitcoins.
Also it is being said that the NSA identified Nakamoto:
