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 ?
They said that Mark Zuckerburg's coin will be released before the second half of this year so my guess is if that really happens and there is a positive response from the world then it will be the start of a bullrun for sure. Just imagine if they use that FB coin for the ads in their platform then that will make that skycrocket in days.
