10% of all Bitcoin's held by five exchanges

According to, an estimated 10,6% of Bitcoin's circulating supply, representing 1,96 million BTC is held by only five exchanges.

The list includes companies Coinbase, Binance, Huobi, OKEx and Kraken. Probably thanks to its custody solution Coinbase stores most Bitcoin. Below a list of holdings per exchange:

1. Coinbase - 944.904 BTC

3. Binance - 289.961 BTC
4. OKEx - 276.184 BTC
5. Kraken - 126.510 BTC

Coinmerce recommends storing larger amounts of cryptocurrency on personal hardware wallets. However, be aware, this means you are fully responsible for the security of your funds, you are truly your own bank.
