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.
the fact that anything can happen at the price of bitcoin. as it is now not expected before, the price could reach faster to $630.
but it was $5,000 in 2017 is not realistic. but in 2020 it was very possible.
