I'm sorry for all the ones looking for speculations, this is not the purpose of the thread. I want to hear from the community about which coins will be making a difference in our world over the next few years.
I would go for Ripple and Ethereum these two has great impact in terms of crypto banking industry and smart projects. These two altcoins are very certain to grow most especially if you hold this for long-term. In terms of price both have not yet reach the peak price, there are lot of room for improvement.
