Having 1M BTC in one single wallet (n enclosed addresses therefore) would be equivalent to currently owning 5,35% of all existing bitcoins to date (some 18,7M). [...]
It is quite possible that either Jeff Bezos or Elon Musk is hiding behind the nickname Newlifebtc, since no average statistical millionaire
(or any ordinary person) will think that 5%
($ 60 billion .. lol) of all existing bitcoins is a small amount. As for Satoshi's million
BTC, in addition to pooya87's rather reasonable answer
[there is a difference between "wallet" and "address" in bitcoin], I also came across one rather logical assumption.
The main assumption is that everytime he debugged his client and updated it, it created a new wallets/files and be didnt back up the previous
take this quote that shows early versions needed backing up entire folders,
(imagine backing up a folder every time you edited a line of code).
4. What files need to be backed up for not losing my "money"?
Version 0.1.5: backup the whole %appdata%\Bitcoin directory.
Version 0.2: you can backup just wallet.dat.
It was just a experiment back then so there was no value in keeping the private keys ... assumptions were that after a few months of bug fixing everything would be reset and born again
(but too many joind and it instead just continued to live and it wasnt until 2010 before h made it simple to backup).
