One important fact is that human imagination is limitless. We are bound to create and discover more things for a lot of purpose.
As mentioned by Einstein in his quote : "Logic takes you from A to B. Imagination takes you everywhere".
It is a result of hardwork and implementation of ones idea, may it benefit the society or be done from greed. There are more cryptocurrencies coming which will create a big impact to the world and more cryptocurrencies that are made out of greed. The truth is, our minds dictate everything.
As far as I can see, there will be more currencies with it bringing more new and innovative technologies which will surely revolutionize the world. I am perfectly waiting for a cryptocurrency that will help our governments systematize their processes with it being transparent to the people.
