It seems that it is still too early for Altcoins to exploding in 2018. Altcoins have been stuck in the red market and most of us are trapped in red traps. I think Altcoins exploding may come true in 2019.
agree with you this is such too early for altcoin making to be explode for well i think this is just an speculation and waiting when could be happen.
If you trace the market from those previous years, most of the time alts explode in the last term of the year so if things happen again then we need
to wait for some months in order to see the value of certain coins that we are supporting with, buy and hold and expect for big increase after btc rise
again, domino effects just in case.
