A lot of people say alot of dumb stuff, but its entertaining at least.
The addresses and bitcoins that belong to Nakamoto or the group associated with Nakamoto are estimated at 980,000 and the estimate is simply based on the theory that he likely mined the majority of coins that where mined at the start that never moved after being mined. Its highly unlikely he was the miner and thus owner of 100% of the mined coins that never moved after being mined and thus he does not have access to all 980k but its logical that he was the miner of 90%+ of those addresses. Hell a few of the addresses are mine, not that I will ever move them since I had formatted that hard drive at least a dozen times in the following few years and then donated the entire computer to the local library.
Most people in my situation stress out being depressed endlessly about how rich they would be if they had been smart enough or lucky enough to never format, sell, destroy their hard drive from the early mining days when we mined thousands if bitcoins easily but the thing is that the logic is totally flawed. If we made sure to keep the wallet intact then we would of sold the bitcoins a decade ago anyhow. Hell as soon as they where worth a nickel each they likely would of been sold.
