In short, the note is saying "Bitcoin will not win by itself. Rather Bitcoiners will win through action they can take using the power of hodling and NGU technology."

Which lead us to the idea that you should never sell your bitcoins.
I wholeheartedly disagree with this foolish philosophy. Change your perspective. You aren't selling bitcoins. You are buying fiat to easily accomplish your goals.
I would rather someone buy some fiat to start a Bitcoin business rather than sit on his wealth and screaming HODL on the internet while accomplishing absolutely nothing.
