thank you all for your replies...
it's the difference in pairs, say btc/aud -10% and xrp/btc -20%, that's throwing me off, i keep thinking they should be the same or much closer and move in sync.... Part of that difference would be brokers fees but is the rest just pure trading, headless, in a brave new world?
What are the things that influence these pairs? Perhaps theses traders have closer ears to the ground, miners, devs, finteks and the like, theyd wanna' have i guess....
