With due respect, Individuals like you have changed the CORE reason Why Bitcoin was created? Trading was secondary part and replacing Fiat was the core reason why Bitcoin was created. Now, it is considered more like a quick way to earn Fiat and become rich.
Yeah right, people are turning the system away from the original reason why it was created, and I feel like before anybody would back his or her argument up as regards the subject matter, they need to first go back to satoshi's whitepaper and read the first paragraph and then some other paragraph that followed it, they will see clearly where he stated the main purpose of bitcoin, and like you said, it is to actually serve as alternative to fiat, not to completely replace it because I am sure that by now, if he had written in the whitepaper directly that the purpose is to replace fiat with it, then the coin would have been in a whole lot of trouble from worlds leader now, but it is you and I that knows that as the system gradually gets adopted, there is possibility of it replacing the fiat in future.
