I have a theory, that some coins influence BTC price negatively,
In the past i felt that once XRP goes BULL, it stops BTC BULL
and now, i see once XRP was dumped after the airdrop, BTC went bull again
So, are we going to draw those conclusions with every event which happens at the same time?
No, thats not how correlation works. XRP and BTC markets are related and effect each other, but that effect is not as big as you've imagined.
Perhaps, both of them represent some sort of global economy turn and one single event effects them in two different directions.
