I even can bet that in next 4 years we gonna see $100 000 price for one BTC
It is exciting to arrive at this price, there will be a lot of people become billionaires, God, it is difficult to imagine that I can hardly reach the price you said. 
Expecting bitcoin value to touch the higher amount is fine but expecting amount seems little higher. I am saying it with the negative thought buf I don't it is possible to reach 50k USD in this era.
Will wait and see for some more years find better value in future.
