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
If you could show us some analysis that your theory that it might be possible then there's really a chance that there's a correlation between between the two cryptocurrency but if there's not I really think that was just a coincidence.
