In my prediction i think every price altcoin is still down because fail and scam project.A good project lock their token to save a fall price. But its not give effect to make their price is up because too little buyer in market.
Will the altcoin raise again in middle 2019 ?
in some way you are right but the unexpected time will be the needed time for a bull Run because if it comes in all time then the hype cryptocurrency will be reduced from the investors so I think the end of the Year will be more perfect for a bull Run.
