If bitcoin wasn't created then i wouldn't be here, this forum would never exist. And no one will be billionaires and millionaires because of bitcoin. Maybe other cryptocurrencies wont be this famous or even wouldn't be created.
Bitcoin is the reason why cryptocurrency is so popular right now. Maybe cryptocurrency would not be as popular right now or maybe would not exist if not because of bitcoin. And the central banks would still have the sole authority over our money. And if bitcoin wasn't created then this forum wouldn't exist and the lives of some people would have not been changed. Many people really profited from bitcoin and many would attest to that.
