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.
In order for this coin to influence the situation of the cryptocurrency market as a whole, it must have at least the same ratings as Bitcoin and Ethereum. But it seems to me that Facebook tokens will have the same pricing mode as other cryptocurrencies today.
