We will see 50.000 at the middle of 2019. Mark my words.
We will see Bitcoin ETF earlier, then price will rise until middle of 2019.
There is actually no need marking your words, as one thing I know for sure, what you have just said will always be a speculation and assumption as no one can see exactly what the future holds. Simply more like you trying to state what you would like to see happen, come 2019.
In a market I have always known, what would be will be and as long as you stay focused, monitor the trends and make decisions based on what you see, then you would not have a problem. 2019 may come with good surprised but however it comes, it is one thing to just be patient and wait for it and then act based on how you perceive it.
