I'm developing an altcoin that is based on social sharing. What foundational technologies are going to make it the most valuable? What makes an altcoin valuable? I'm wondering if it is just how much people hear about it? Thoughts?
If you mean coin with real value, and not inflated by hype and empty promises, you have to create something that people are going to use. And for that the coin has to bring features that will solve people's problems.
Lately, what I've seen is that users have been looking for something that brings anonymity and scalability. If you manage to innovate in that area, you greatly increase your chances to succeed.
