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
Have you forgotten that the market is unpredictable dude? also when Bitcoin goes up most of the altcoins dump their price value
in the market as well, only few of the altcoins follows the trend of bitcoin price like Ethereum, and more this was happened a couple of years
now in this field of business.
