What you said is the actual truth and all altcoins growth are dependent on the Price of bitcoin. When it comes to the cryptocurrency world Bitcoin is the king and nothing can change that for now. There is always a ruling party in everything we do so i guess is no surprise that BTC is the ruling party when it comes to altcoins. When it comes to pump and dump and whale groups those are the forces really manipulating the market. This market usually called high-risk, they say, investing money in it involves the expectation of high incomes, but also with increased risk. Capital behaves exactly the opposite - in BTC (and therefore, given the positive correlation between the crypto, and in all kriptonok) there is an increase in investments when capital sees the danger of slowing the growth of the world economy.
