wow. So if someone has looked, could you summarize the history of the sending address? (When did it have transactions, etc.)

Also, if someone wanted to turn this into fiat currency over a short but not instant period of time (such as 1 month for example), could they get close to 1,018,147,922 USD or even over 30 days would that diminish the price too much?

(I am thinking for example if an institutional investor early on bought 94,504 bitcoins and "just realized" they have it or something, but only really cared about dollars or their fund is over and they have to pay out the cash or whatever. For whatever reason, if they want cash now.)

Thanks for any expert opinions.
