Satoshi never cashed out (unlike every other founder in history and I bet that it never happens again)
Satoshi created bitcoin for the world and he never even cashed out. He did it for us and he didn't even profit from it.
Now that everyone knows that cryptocurrency can give you money, everyone started thinking of cryptocurrency only as means of profit so it is truly impossible to encounter a founder that would not want to benefit from his own creation
Even I would want to cash some profit out
Bitcoin is a brand
Some might not know what crypto is but they might have heard of bitcoin
You are correct that bitcoin being the first one has created a brand for itself and paved the way for the rest of the coins to continue on to
It is a lifestyle now that more and more people are adapting and it might not be the best choice of cryptocurrency in the future but as of now right as we are speaking bitcoin is the most well-known and that is not easy to defeat
