Yes, and I'm staying positive myself, but how high could bitcoin's price rise by the end of 2019? Do you think this $4000-6000 will stay as the new normal for bitcoiners next year? Can we expect a little raise, maybe up to $10k, hopefully?
Let's put it this way..
You should not set a target date for such expected price target because it will destroy your expectations. If you truly believed that bitcoin will soon bounce back just let the progress run and do your assignment on how to take advantage of it.
If your purpose is to just hold, then you must work on acquiring on it no matter the method is.
No one knows what will happened in the future. Set a goal and stick on it.
