I think it will barely pump as altcoins value will follow on bitcoin's growth. The current market phase has already shown a good sign of bull trend and I believe that a midst of 2019 is the unbreakable bullish trend, just what had happened last 2017.
bitcoin is now really very strong, growing with a very high value. Altcoin should have followed a lot of this growth. so does ethereum, but etheruem growth is still very slow.
therefore now many investors are coming in to join in investing again into the crypto world like bitcoin and ethereum because they believe that soon the two coins will experience high price increases and to get a profit that promises to be very easy
