I'd love to learn more about cool projects and concepts that could be the evolution of blockchain (again, not altcoins please 
)
This is cryptomarket where the top coin is Bitcoin and the rest are considered altcoins, so you mean you are looking for another Bitcoin? I guess it will not happen in cryptomarket, maybe on a different market but not here. Cryptocurrency is still the trend and it might last longer, it will be hard to compete with Bitcoin where all the cons already compliments by the altcoins, Satoshis mind are already out with the good altcoins developer.) even Ethereum which is the 2nd ranking coin in CMC it will still be difficult,
but in crypto sometimes things that we don't predict can happen
