I would have said $40,000 bitcoin's were an absolute dream but the way the price is rocketing at a seemingly unstoppable rate I don't see $40,000 as dream land any more. It really could become a reality sooner than we think.
You would be surprised how likely it could be that we would see ridiculous prices like the 40000$ price. If bitcoin were to get a mere 5% of the total amount of money that people have invested in gold bitcoin could be valued at $25000. And that's only 5%! With the current growth 25000 can be likely in the next 3-5 years (realistically speaking and a lot of the times I'm wrong when it comes to prediciting how soon bitcoin will hit a certain price point, perhaps at the end of next year who knows).
