I think cryptocurrency will have a bright future, right now it is slowly making an impact on everyone that will be huge in the future. More and more people will recognize this and more people will use this.
Now I see that cryptocurrency does not bring any value to the economy. So that I will believe that in the future, the behavior of the people will change and they switch to use cryptos for the transaction daily, for example, buying goods in the supermarket, paying in the restaurant, etc.
It brings value in the form of security! People need a safe place to hold their money.
Not all of us can afford a safe and banks aren't as safe as we thought them to be. Most of us can afford a hardware wallet and all of us have mobile phones capable of running a crypto wallet. This is the real value and this is the future! You don't have to produce physical goods to add value to the economy.
