Do we know when the word "bitcoin" appeared for the first time? Are we 100% sure it was in THE PAPER?
The domain name bitcoin.org was registered two months before the whitepaper was released.
This is correct!
The domain name was registered before the bitcoin white paper was published on 31st October, 2008. However, the whitepaper could be regarded as the first official register for the name bitcoin.
I was thinking why not “dollar”, as in fact it isn’t one-country currency and we have several “dollars”, digital dollar would be a possible choice too (and somehow “closed” the name for centralized gov dollar).
Satoshi was already conscious of his creation before he created. He was aware he wanted something not centralized that is why he didn't go the way of dollars. He had a clear vision of solving the problem created by centralized fiat, it wouldn't make sense naming his project with the name of the sickness he wants to cure.
With his conscious mind, that is why he choose a pseudonymous name and was able to conceal his identity till date. Nothing took him unaware and nothing happened coincidentally.
I think that the word 'bit' is a know computer lang, but it is well connected with Sats as a unit of bitcoin. Which shows that it is a currency that will still be valuable even in thousands of bits. Maybe from here the 21 million cap was formed
