If you ask from me then I will say that watching the current rally, $10k is also looking small for price of 1 bitcoin in year 2020.
And I hope the support and the bullish behaviour never ends and bitcoin will be the new money that the world will be using.
Sure,if bitcoin continues to rise in this speed,it would definitely cross $10,000 by 2020.Bitcoin has created a revolution in the world economics.It seems that it would still continue in the bullish trend.
