Everything within The Universe is either in a State of Expansion or Decline, both of which are Parabolic in nature.
Parabolas can be applied to anything that changes: Rate of expansion or decline, population (the higher it is the greater the growth and of course visa versa), technology growth (something to do with Moore's Law I believe) and of course Prices, and here we are talking Bitcoin .
Bitcoin is not just a digital currency, it is also a measurement of the (see above) of Technology, part of which is Blockchain Technology which is being taken up and utilised all over the globe for many purposes with the financial sector being heavily involved.
Countries, Banks, Payment Systems, you catch my drift... are all examining and taking up Blockchain Technology, some of this massive and adoption is Bitcoin!
Note that a parabola is best fit to the data and then therefore maybe a little skewed. Hey nothing runs smoothly in life all of the time!
The more 'perfect' the parabola (less skewing) the greater the accuracy of the trend.
Be warned, when parabolas cross (see chart) they give a strong and almost undeniable end of this parabola's phase and the beginning of the next one. At this point the in the opposite direction is rapid.
The next parabola cross is in August (15th on chart) 2021 which will have a Bitcoin price of just over $52,000. After this I would expect a rapid correction as the next parabolic phase starts and then, in time to come... :)
The question of course is: What event(s) will occur that causes the rapid in August (chart predicted) 2021?
