I don't say that economy is going up and up everyday. Maybe in other country. But not all country is have a good economy. cryptocurrency as of now is good to know that have change a lot and still up so many people in their economy is interesting to know about this.
I think this is another function of cash is to be a currency exchange tool for cryptocurrency, so the selling value of cryptocurrency can be used for in the real world.
cryptocurrency is now much in demand, some people consider cryptocurrency as a valuable asset to them. but cryptocurrency has one weakness that is not the official currency. cryptocurrency is just a virtual currency in the digital world.
This is true and as such majority of the population over the globe still are hesitant to either invest to it or is still afraid of it because of volatility. There are also people who do not believe in its potential but I think that the next step of cryptocurrency is to integrate its usage to society not only it will lessen the volatility in the market but it will also attract more investors.
