The five biggest cryptocurrency trading platforms control 1.7 million bitcoins, according to data from Chain.info. That amount equals about 10% of all bitcoins in circulation.
Coinbase leads the pack. The US exchange holds 944,800 bitcoins across 4.38 million unique wallets, with 944,200 in cold storage, 623 in deposit wallets, and only 0.1 BTC in hot wallets.

Huobi ranks second with 324,000 bitcoins spread across 901,000 wallets. Binance, the world's largest platform by trading volume, holds 290,000 bitcoins in 2.67 million addresses. OKEx has 226,184 bitcoins in 339,000 addresses. Kraken, the other major US exchange in this group, holds 126,500 bitcoins across 672,286 addresses.
According to CoinMarketCap, Bitcoin's total supply stands at 18,517,643. Blockchain analytics firm ByteTree puts a more conservative estimate at 16,969,840 bitcoins in adjusted supply.
Using the CoinMarketCap figure, the five exchanges control about 10% of all bitcoins.
Earlier this year, Chainalysis released research examining where bitcoins reside. Investors hold 60% of supply—about 11.5 million bitcoins—as long-term holdings rather than for trading. Traders move another 3.5 million bitcoins back and forth between investors and platforms. If these numbers hold, the five exchanges contain 50% of all bitcoins meant for active trading.
The remaining supply doesn't fit neatly into any single category. Analysts classify about 3.7 million bitcoins as lost, though that estimate may overstate the actual loss. Bitcoin miners from 2009 moved some of those old coins to market in 2020 for the first time, suggesting some coins once written off could still surface.
