Isn't it way too early to predict about 2k19 bitcoin price, when we are not even sure about what is going to be the market scenario in the 2k18 end. Well USD 30000 doesn't seem like coming true soon. However you never know for the crypto market, how volatile it is...It cannot be predicted with perfection in advance. This continuous dump in the prices of the bitcoin is combined result of so many factors, so this is wrong to say that the same situation will keep on continuing for the years to come. Maybe 2019 brings a new era for the bitcoin industry!!
