A lot of people will be using this coin but I would not say almost everyone, there are still people who are doubtful about bitcoin and cryptocurrencies and banks and companies will do everything they can to hold it down.
If you are still worried about people's doubt, it will be a thing of the past very soon when people will no longer be doubtful but only angry that it is too expensive when they end up finding out the price some people even got 1 BTC at today's price. Gradually, the currency is being recognized in most places, I even read recently where Pacific Nation of Vanuatu is accepting bitcoin for citizenship and it is going to keep getting better.
