1btc is not stored in a tx, block or blockchain data as '1btc' at raw data format
a bitcoin (1btc) is an allotment of 100,000,000 units of sats
(gold is a bunch of atoms too)

inside a transaction at raw data level converted to human readable numbers
everything in bitcoin network and transactions is measured in sat numbers then divided to its btc representations

so then looking at a tx of 1btc. in binary.. which is the true real world state it sits physically on a hard drive in:

101111101011110000100000000

so 1btc physically looks like  101111101011110000100000000

or if you were to use a microscope looking at a hard drive platter , at an angle of its horizon

as for referencing it on the bitcoin blockchain. in human readable form

you can reference your txid you received 1btc from where its output to your address shows the 100,000,000 at raw tx data level

or even more human translated form on any blockchain explorer/wallet showing you your transaction receipt in btc allotment amount
..

by the way.
gold is just a bunch of atoms too

i suspect the topic creator is actually snowshow using yet another alt account. trying to play dumb to introduce himself as an idiot yet again to then try pushing his "bitcoin does not exist " troll game.
