Definitely bitcoin price will be going up day by day. I personally believe that, by the end of 2018 bitcoin price will be 40,000$+. So I already go with btc & hold some dollars for future.I have no doubt & I know bitcoin future is very bright. I suggest you to do the same. It's great opportunity for us & also best time for take effective steps. Wish you all the best.
Definitely it will be best if prices go up day by day but always prepare for rainy days and have enough cash flow to do what you want to do in time of any situation.
