There is definitely not a single chance that bitcoin does the same thing over and over again every year. This year the price wasn't that high on may and it was definitely low in June however the previous year it wasn't like that and may was a high and June was a drop because of the bitcoin cash problems and the price dropped and increased back on October or so.

This means we should definitely never consider bitcoin will ever to the same thing over and over again every year. It won't insanely go up this December, it may not go low next summer, the price will not repetitively do the same thing, every season is different from each other and every year is different from each other.
