2) Govts and Banks would have taken full advantages during pandemic
What are you talking about? What advantages during the pandemic? The governments got into bigger debt and the central banks printed billions of fiat money. Online banking got a short term advantage, but now the pandemic is pretty much over.
4) The excitement to grow money 10-20 folds would have not existed ...
The excitement of growing your money 10-20 times existed way before Bitcoin/crypto. People, who had developed successful companies or are really successful at playing poker have witnessed 10-20 times increase of their wealth.
No Top Business man can claim they made money by playing poker, but yes if you dont care about elon or saylor they are specific in claiming that they have made million by investing in bitcoin
5) Top Business House and Influencers, such as Michael Saylor or Elon Musk would have been obsolete with just a few tweets...
Who cares about Saylor and Musk?
It doesn't mean if you care or not , but yes world cares ..at least those who are following them and 90% people follow them not because of their business but for their love and hate about bitcoin or other crypto currency ...when did people know about Michael Saylor and others
6) The search for a person (Nakamoto) , was never been so much anticipated by the whole world, probably like the "Wealth of Rothschild"..
I'm sorry to say that, but nobody cares about Satoshi Nakamoto, except a bunch of fanatic diehard Bitcoiners, who think that Bitcoin is the best thing invented since bread.
If today, The real Satoshi Nakamoto would appear ... i would presume that the world media would cover him and give him more or equal importance than attacking of twin tower by Osama Bin Laden
In summary, almost nothing would have changed in the world, if Bitcoin wasn't created.
