The guards do everything in increments of 21 like taking 21 steps, pausing for 21 seconds. It’s in homage to the 21 gun salute. Which happens at a soldiers funeral when they’re buried with honors.

Coincidentally I dreamed last night about showing someone the shells I have from my grandfather’s and uncle’s 21 gun salutes.
21 million bitcoin, wierd coincidence eh?
21 was my basketball number. 21 is also the age where you can legally drink in the US. You could probably find lots of reasons why the number 21 million was chosen.
Maybe 21 was chosen because it’s a triangle number and the triangle is the strongest shape.
We’re also in the 21st century
1 + 7 + 7 + 6
Ooo another option. Assumes Satoshi is from the US. Or do you believe the theory that it was created by the CIA?
My ‘real’ opinion is that Satoshi picked the starting mining reward at 50 BTC and 210,000 blocks/halving, and ~21 million BTC is the result. It could be that Satoshi picked “a value for blocks/halving such that you get a similar looking number for total supply.”
The 21 gun thing predates the US, but I’m told that the “1776” interpretation is a common interpretation meme given to it in the military. 🤷♂️
Writing this out, I realized it’s wrong 🤣
