btc is like a mother for all altcoin, but not all altcoin price depend in btc price, not like altcoin who still controling by company, btc pure dezentralized, so the price pure from who realy need for transaction.
Bitcoin price definitely impacts the alts because all the alts pair with Bitcoin or Ethereum and the price of Bitcoin rise or fall should be affected as per my knowledge in this. It is not a good sign actually but there is no other option for alts as of current market situation.
