At the moment we think that he is a savior and helps us to gain financial freedom and protect our privacy
Not at all, we know that
his creation is doing all that not him.
At the moment, Satoshi has around 1 million bitcoin.
Wrong. That amount is your
imagination guess. We have no way of knowing how much bitcoin anybody has, least of all someone who we don't even know their real identity!
In other words you don't even know who Satoshi is, how can you claim to know how much bitcoin he/she owns?!
What if it was created by one of the worst person ever? What if he wants to make us dependent on bitcoin as much as possible and one day he comes, sells all his coins and causes financial catastrophe.
What if it was created by persons like Mark Zuckerberg, Bill Gates, Jeff Bezos, etc. These are the people who don't respect their customers' privacy.
Your problem is that you only know bitcoin as something you invest in and has some price whereas bitcoin is not that at all. Bitcoin is a censorship resistant currency that has been operating globally without any restrictions. What its volatile market does in short term does not affect its nature.
