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
yes, but not only ripple. all altcoins will experience the same thing if bitcoin is being pumped. ripple is having a slightly bigger impact because XRP has already completed its snapshot, people are sure to sell it right away to buy a more profitable altcoin. but look at today the ripple has started to return after yesterday's decline.
