if we take into consideration that the address of satoshi nakamoto contain up to 1 million bitcoins, we may think that the amount of burned BTC is over 1 million now, since its safe to assume satoshis keys are lost for life.
some people believe satoshi mined 1-1.5 Million BTC
i have seen analyists thinking that 33% of the bitcoins maybe "lost" but i guessitwill take some decades to see if that is true
it is wrong in my opinion to think if someone didnt sell for $1250 then his coins must be must
many investors are likely fiat rich and dont need to cash out until something drastic happens in the economy
