Sometimes, we just need to dig dipper and understand the real purpose of a new tech, but most of us are unable due to our lifestyle, too busy to pay attention and must focus on the things that are more important (that's what the typical person's think in my country when there's a new trend in technology like cryptos). Let's just have to wait until the time comes for these cryptocurrencies and it's acceptance.
Some countries are not into cryptocurrency and digital technology. They are negative when it comes to digital currency/ virtual money because they prefer the actual physical money that everybody is used to. There is always a right time for everything, in the coming years it will be known to then and slowly they become used to it and would surely accept it as the new trend in digital technology.
