I believe even if it's in 2019, over time, everything will be even better than where we are now. We can't say specifically how 2019 will be valuable, we can hope that this will be a better year than this is in terms of btc value and the opportunity to get good profits from it.
Its good to be an optimistic mate. There is no doubt that bitcoin will arise even better this coming 2019 and reach the desirable peak ,maybe $30k or more over. Even the reamaining months of this year has a huge of chances that bitcoin will start to progress the development prices. And will excel as a king of all currencies in crypto world.
