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 ?
Predictions can be wrong but seeing the bitcoin movement that has begun to move towards the better has begun to be seen even though it is still not in a big breakthrough, still little by little to lead to becoming better. I agree that in the middle of this year the movement will start to improve and continue to move even better until the end of 2019. But to repeat the same as 2017 will be difficult to achieve, maybe around $ 7K-$10K.
We are all waiting and anticipating good movements coming from this small reversal, if this can sustained and new support barrier will be more stronger we do expect that the amount will go to that level, it's just the people/community behind that will bring the bull to wake up after gaining more buy pressures than the sell momentum,.
