I like to read different methods of pricing bitcoin. I came across this one on reddit which points to $7,500 as a top. Permanent or short term top, who knows. But his logic is interesting. Remember – see both sides.

Bitcoin Will Crash Below $3000. https://bitcointalk.org/index.php?topic=2396770.0

Bitcoin rises from $611, June 2016, to the current price of near $8000. This is an exponential rally, a rise with an accelerated rates. Such a rally defines a market bubble as it will very quickly reach a level that cannot be sustained – when the bubble must burst crashing the market. The past examples are the Dutch Tulip Bubble of 1637 and the Dot.com bubble of 2000. Such bubbles always bring prices to levels where it started.

That exponential markets must crash may be just a simple law of nature. In order for such inflated prices to be maintained, there must be some support from the underlying fiat money supply. The maintenance of trading volume means generally a greater money supply allocation to such a market; it is likely such cannot be maintained at a point in time causing the market to burst.

I have done an exponential curve fit of bitcoin prices from 2016/10/6/611 to 2017/11/16/7843. Extrapolation of the exponential curve (y = A exp (kx)) is done and the figures shown below.

The extrapolation data may be used to predict when the bitcoin bubble may burst. The method is to make use of proof by contradiction. It makes an assertion X; then it uses deduction logic starting from X to arrive at other statements of truth. If if arrives at a statement such as : 3 < 2, which is clearly false, then a contradiction exists refuting the assertion X. We can us this method on the extrapolation data.

Assertion : Bitcoin can reach $507,532,895 in five years, by 2022.

Unlike in mathematics, we cannot here make deterministic deduction using pure logic. We can only make a judgment based on our common sense and intuition and say how likely something may happen.

Most of us very likely would dismiss bitcoin at $507,532,895 by 2022. So we try other extrapolation figures. Say we also dismiss $5,564,849 in 2020, 3 years from now. So when is this bitcoin bubble likely to burst.

The price based on the exponential trend has the figure $6389, days 0, 2017-11-16. We are now doing at $7800 at this point which seems too high above trend. In the least there should be a significant correction – or it may even mean this:

Bitcoin bubble may burst any time now.
