Lets think positive and so do expect Bitcoins for an upward movement. Currently seeing the price, and the past graphs, its 100% sure that Bitcoins will move up in the December. I mean it wont fall down atleast. If Bitcoins anyhow manages to touch 20k usd by the end of this year, the definitely we gonna see a good growth in the next year. So I am advising each and everyone to buy as many Bitcoins as you can in this bear market price, later when price goes up, we will regret for missing the golden opportunity to buy Bitcoins in cheap.
It's not completely going to go up 100% in december even though it's down to $20k because bitcoin is still in support at $16k today it's slightly inclined to go up to $17k but it doesn't last long and it's below that again which is clear I predict still under $20k in the month ahead.
I know this has to be a positive thing about the market, and I would not pass up this opportunity to buy low and hold it, but some traders take advantage of opportunities with a small upside it will be a valuable advantage for them.
