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).
The next time we should expect to see some interesting
BTC price highs should be between December and January... and the lows between June and October.
Miners can weigh in on this, perhaps...
I don't really think seasons have much to do with this. How are you stating that miners affect the price? Are you saying that the more miners there are, the higher the price can go? Or are you saying that the fewer there are, the higher the price goes? There aren't many grounds that you've made in your first statements.
I'll assume that you say that the more miners/mining is happening, the higher the price goes. However, the opposite of this happened last December. The mining fees were absolutely insane because there weren't enough miners to keep up with how many people were flowing into the whole crypto scene.
