Bitcoin Pullback and Parabolic comparison

I see a lot of comments at the moment regarding pullback or retest.

'Ooh it's rising too steep, it's gonna crash!'.

'It hasn't pulled back, it won't go much higher'.

So here is a quick comparison from 2017 on the left and current price on the right.

in 2016-17 we saw an increase from 600 to 1200 with a pullback to 750
Then up to 1300 and another pullback to 900.

However, after that the price doubled to 1850 with only a small pullback before rocketing up a very steep curve to 2700 before a larger pullback.

Please keep this in mind when trying to catch the top shorting this.

If a similar pattern happened now, the pullback to 6600 could hit 12000 before another retest.
