Ethereum price will increase but we have to wait patiently because last year the price of ETH increased more than 1200$. People who are holding ETH for another year definitely they will be in profit.
If you sell ETH in this period, they are definitely speculators and only interested in immediate profit but if you are a long-term investor then surely in 2019 they will get a lot of profit because I I believe that with the participation of the ETF, the value of all coin will go to the moon
