Who holds the most bitcoin?

Last Thursday, Bitcoin's value surged past the high of $8,000 to hit a new all-time high of $8,500 on September 5.

This impressive feat made those who had invested in bitcoin millions of dollars richer — and it was Facebook CEO Mark Zuckerberg who held the most in his own digital wallet. It is unclear if he plans to sell any shares or if he will continue to hold onto them; however, as of this writing it is still his largest investment.

Bitcoin Investment Trust (OTC:GBTC) was the only other holder of bitcoin in Zuckerberg's digital wallet. This is something to note as bitcoin value has been rising. And, as early as September 1, it is estimated that Zuckerberg held more than $11 billion worth in his own bank account.

Second on the list was his wife Priscilla Chan; however, she does not appear to be holding much more than a million dollars on her account.

Zuckerberg isn't the only one who has put his money into bitcoin, either.

Back in July, it was uncovered that Cameron and Tyler Winklevoss, the twin brothers who claimed Mark Zuckerberg stole their idea for Facebook (FB), had purchased nearly 1% of the world's supply of bitcoin. The twins purchased the 1% at $11 million. It is estimated that those same coins are worth over $1 billion today.

This is where the Winklevoss brothers entered into a debate, though. The brothers allege their investment was taken from them, and that's not all. In the battle to keep their stake safe, they have sought to get a settlement out of Facebook. This case went all the way up to a New York judge (which has now been settled) who ruled that no one could block their access to $65 million in cash by keeping these coins in cold storage (a type of online vault). Facebook, though, had invested in Gemini, a digital currency exchange that provided custodial services for the twins' coins.

As soon as bitcoin started to take off, a handful of other billionaires started pulling their money out of bank accounts and into bitcoin. Between them, these early adopters own over 1% of all bitcoins in circulation.

Then there's the Winklevi's case, of course. Mark Zuckerberg is one of the early investors who acquired bitcoin and had his stake stored on Gemini. As such, he is the largest single owner of bitcoin in the world.

As quoted by Business Insider, Zuckerberg stated that his reason for acquiring bitcoin was to get a hold of a different currency than the U.S. dollar. In other words, he wanted something outside the traditional banking system that could not be easily manipulated by governments and central banks nearly as much as fiat currencies can be; however, Zuckerberg has yet to make any statements about selling or transferring his holding.
