Don't think we can expect much from altcoins this year as Bitcoin seems to be the only cryptocurrency in a full speed heading for moon lol. I think altcoins might have their turn getting to the end of the year or probably when we enter 2020 in the first quarter we might see the whole crypto market rise.
It could happen, bitcoin has been the only coin that has been consistent performing thus far, but at least this is better compared to last year where the entire market is so bearish. It would be nice to see that somehow the market is still productive in overall as bitcoin which is the dominant coin is making it's big recovery.
In comparison to 2018 we've been experiencing good growth with bitcoin as well altcoins. When we say altcoins it comprises of just 25% of the available ones, as the rest hasn't shown any big movement with correspondence to the growth of bitcoin. 2018 was expected to be the year for altcoins, nothing big took place. Now once again same seems the scenario. It is perfect time to invest as altcoins with good potential too is down.
