As per this page https://runonflux.io/mining.html and the white paper that i have seen a year or so ago, flux follows bitcoin halving block reward, like ravencoin, I see no huge increase in price, it will follow bitcoin just like ravencoin. I see no aggressive roadmap on flux or ravencoin, so I guess developers on those coins are just taking it easy for the long term. So we can expect an organic rise for both of them, ETH with pos and burning, ERGO with decreasing block reward every 3 months and both being still pow, that is very aggressive, eth will soon go pos, my take is, eth will go pos before the next bullrun, year before the next bullrun at least. ERGO on the other hand is extremely aggressive, I call that "suicide move", the question is if the market will follow that suicide move, miners will only follow if there is profit.
