It seems that the altcoin next year is still in the process of recovery and has not been able to increase too high. So it's better to stay patient and use good opportunities to make a profit. Very difficult development and will continue to get higher grades.
Were not certain if altcoin would truly increase by year 2019. I think some alts will surely increase with development in their project. Some alts will die and some alts will survive so lets observe and hope good about altcoin.
