There are a lot of Altcoins, any year is a good year for an Altcoin that was pumped or just really got a promising future.
Naming a Thread "2018 is a great year for Altcoins" is pure nonsense, there are tens of thousands of altcoins around.
At least name the Specific Altcoin that will become profitable this year.
One thing you must learn is: These unregulated non-legit exchanges dictates the price of an altcoin.
Those are susceptible to manipulators like Pump&Dump Groups or Whales
Even Bitcoin's price can be manipulated.
But one thing is for sure, Either XMR or ETH will rise this first quarter of the year.
I agree. I think that it is really a good year, in the outset at least, because there are so many developers gunning to pump the value of their coins and increase their market caps as well. Many altcoins, since the surge of bitcoin during the last quarter of 2017 ended, are beginning to recuperate and gain back their value and market power, which is good because it makes the market active again.
