I would like to share my very first idea here. It's probably more "food for thoughts".
To my idea:
This is a 15Minute Graph of Gold & Bitcoin
I recognized a correlation between Gold (and any other Big Metal) and Bitcoin .
I found this correlation actually at a much larger scale in a , but once I was "zooming" in the correlation got even more obvious.
My first observation brought me to the idea that money is beeing swapped between gold and bitcoin . But the fact that the approximate Market Cap of gold is somewhere around 7 Trillion USD makes this theory quite jabberwocky.
Anyway the correlation is there, but the reason must lie somewhere else. Maybe you have an idea?
