I'm so happy to read so many people disagreeing with it so boldly. This means it has become a really realistic possibility because the majority is always wrong.
You know that this is not going to happen soon, if it happens then I am going to be shocked that is for sure. For the price to be this high is possible in 2017 or 2018 but not now.
You said 2017

as if it wasn't soon... it's less than a year till 2017
2017 is just 6 months away. But I think the price will not be $5000 in 2017. If it does reach that level, it will also drop to $500.
bitcoin has seen much larger rises n a short timespan.
for example a 100 time rise in 11 months.
nothing is impossible, and if we get similar rises again we could easily see $50,000 by Q2 2017.
It's not even that unlikely, considering the long bear market and the halving and all the infrastructure improvement and investments since the last big peak.
If guys like Tim Draper conservatively believe Bitcoin will hit $10,000 by 2018, anything is possible.
I believe the Brexit doesn't look good for the future of the Euro fiat currency. The US dollar is no longer backed by gold, and it seems the logic is that it is too big to fail. Unfortunately you can't earn any interest, and they just keep printing more every time there is a bigger debt problem. We could easily see another financial meltdown in the near future with no way out this time.
At some point it will be Bitcoin to the rescue.
Decentralized currency continues to look better and better
