I expect a lot in 2020. I think this year will be similar to the end of 2017. At least something close to this.
I also think that in 2019, major market players will gain positions in cryptocurrency assets and begin global growth of the entire industry. Bitcoin should overcome the mark of $ 20,000 and Altcoin's capitalization will be more than $ 300 billion.
Already the market dominance for Bitcoin is completely high and this makes most of the altcoins decreased their prices. Now we are in Q4, which we might see altcoin prices will start recovering because Bitcoin dominance is gradually decreased due to a sudden drop in the market.
