"All of those are good coins," <--- I beg to differ with Reddcoin (despite antagonising those holding it).

Its idea is good - something like Steem/Steem Power where contributors at social media (Twitter etc.) get rewarded by others upvoting. But the window to implement this had passed.

Reddcoin has become a pure speculation play nowadays. Not that one won't make gains. For this he only needs for other speculators to bid up the price, and cashing out. But project-wise, I doubt it will ever achieve its stated goal of existence.
