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 ?
I don't think that's true at all. Yes some coins are scams or pointless money-grabbing projects that don't even need to be crypto.
But there are plenty of alts that are real projects, with a genuine use-case, a solid team and roadmap, etc.
It's just not true that all alts are scams.
We don't need to argue this, the truth is there are successful altcoins.
This entire
market except BTC are all altcoins and if you look at them, they also have a volume because they have a good team. Also, don't forget to check these successful project using tokens,
