Binance: A Bitcoin Behemoth Binance, founded by Changpeng Zhao (CZ) in 2017, is a titan in the crypto world, holding an estimated 633,577 to 663,813 BTC as of 2025, valued at roughly $40 billion to $60 billion depending on market prices. Most of these Bitcoins are held in custodial wallets on behalf of millions of users, not owned outright by Binance. The exchange’s massive reserves highlight its role as a liquidity powerhouse, facilitating trading and driving market stability. However, its 2019 security breach, where hackers stole 7,000 BTC, underscores the risks of centralized exchanges holding such vast amounts.
CZ himself is a notable figure, reportedly selling his apartment in 2014 to buy $1 million worth of BTC (around 1,300 BTC at the time). While his personal holdings remain undisclosed, his 90% stake in Binance and influence in the crypto space make him a significant player.
Other Major Bitcoin Holders Binance isn’t alone at the top. Here are some other key players dominating Bitcoin ownership in 2025: Satoshi Nakamoto: The pseudonymous creator of Bitcoin holds an estimated 1.1 million BTC, worth over $94 billion. These coins, mined in Bitcoin’s early days, remain untouched, fueling speculation about Satoshi’s identity and intentions.
Coinbase: Another major exchange, Coinbase holds around 960,342 BTC, primarily for its users. Its role as a custodian for U.S.-based Bitcoin ETFs further cements its influence.
MicroStrategy: Led by Bitcoin evangelist Michael Saylor, this business intelligence firm owns approximately 568,840 BTC, or 2.7% of the total supply, valued at over $46 billion. Saylor personally holds 17,732 BTC.
BlackRock: The world’s largest asset manager has jumped into crypto, with its iShares Bitcoin Trust holding over 530,831 BTC, reflecting growing institutional adoption.
U.S. Government: With around 205,515 BTC seized from illegal activities like Silk Road, the U.S. is the largest government holder, often auctioning these assets to the public.
