Maybe it is them who are shorting bitcoin between 6k and 8k.

Stop falling for bulltraps and buy only outside of this range.

Markets are constantly in a state of uncertainty and flux and money is made by discounting the obvious and betting on the unexpected. George Soros

to be totally honest with you i do NOT see any relationship between months (seasons) and bitcoin price whatsoever.
i know that there are a lot of  theories about this connection and how some claim certain trends exist but in the end i consider them more of a coincidence than anything else.

and as a proof i think this year is a good proof. every year we had a drop in Jan. and Feb. and then price picked up in Mar. and April but this year nothing is happening!

I would not totally reject the theory about the seasons,it definitely affects people in many ways.Let's say that the winter is maybe time when people spend a lot of time in the indoors,and accordingly to that spend more time on computers/internet-but in the winter in the northern hemisphere we see that it is always the toughest part of the year for cryptocurrency.So it might be connected with Christmas-New Year holidays when people typically spend most of money in the year,and sell crypto for fiat.

On the other side at the end of the summer and early autumn people start to buy BTC just because have somewhere in the subconscious they could profit in few months and have more money for the holidays.Between all this is the summer and long-awaited annual vacations,time in the year when most people leave BTC for some time.

I can tell for myself that I'm much more active online in the winter,but how come the warmer weather I spend more and more time outdoors and I assume it is similar to most people(at least for those who have seasons).

Owing to the Earth's axial tilt, winter in the Northern Hemisphere lasts from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer lasts from the June solstice (typically June 21 UTC) through to the September equinox (typically September 23 UTC).
