I would not be like this, who can buy what I want if Bitcoin is not created, and I will not be able to recognize blockchain and crypto technology if bitcoins do not exist, and it's probably true that the crypto world will not be known much without Bitcoin.
In my opinion, If Bitcoin wasn't invented it wouldn't make a big difference right now. I don't think Bitcoin is currently actively affecting a lot of lives. Sure, there are some exceptions but I think a majority of people see Bitcoin as a curiosity. In any case, paying with Bitcoin or any other cryptocurrency doesn't seem that appealing to me when it's so volatile, and I think that it's going to take a while before any of the currencies are stable enough to be a payment method. Being a viable payment method would deliver on their promise to cut out the middleman, but at the moment cryptocurrencies mostly seem interesting to speculate on.
