Mark Cuban said in an interview: “There are some problems with cryptocurrencies. When most people think of cryptocurrencies, they think of speculation. That’s not what cryptocurrencies are really about. The real point of cryptocurrencies is to create new applications, Make things better and simpler. What cryptocurrencies are missing are apps that even grandma would want to use.
Think back to the iPhone, which came out in 2007, but it wasn’t until the best apps like Instagram and Snapchat entered the market that the App Store and iPhone really took off. Cryptocurrencies are still waiting for their Instagram moment. "
