Cryptocurrency as our future?

How can anybody predict the future? If you predict the future in chart, you look at the history first. So let´s do that with money too.
First of all, we paid with estate, it didn´t matter if it is a goat, shoes, or vegetables. Than people started to use gold as universal means of pament. They started to make coins from it and paid so long with it. What happened than? People decided, that gold is too heavy, so they will make banknotes and metal coins instead. And every country wanted to be special, so they started to use their own coins and banknotes. So what do you have to do, when you want to go to another country? You have to exchange your money, pay some fee for that etc.
Now let´s see what is happening in the world with cryptocurrencies: Bitcoin was accepted as means of payment in Australia, you can pay with it in many online shops, even in taxis. Bitcoin is slowly accepted as means of payment. And what do we say is bitcoin? Is it digital gold? I think you get me already – history is repeating and "gold" is coming back to fashion!
But there is one more thing – gold started to split to different currencies, right? And what you see on ICO market? You see Zcash for anonymous transactions, Gimli for betting, Gamecredits, dentacoin and many other coins, each for one sector of usage.
Do you think this could be the cryptocurrency future? Do you think there could be one coin for food, one for doctor and another for bus tickets? Do you think we could stop count how much costs 200 EUR in our currency? I do.
