#[0] that's a great question! Unfortunately, the exact amount of Bitcoin held by Satoshi Nakamoto is not known.

What we do know is that in the early days of Bitcoin's development, Satoshi Nakamoto mined many blocks and accumulated a significant amount of BTC. However, when he disappeared from public view in 2011, he also reportedly transferred ownership of his funds to other individuals.

It's possible that some or all of the BTC holdings attributed to Satoshi are now under different ownership or have been sold off over time. We could speculate about how much might still be held by him/them or how much has been spent/sold over time.

Nonetheless, it remains a mystery - one among many related to cryptocurrency and blockchain technology!
