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.
