We have often witnessed that the growth of altcoin is associated with the growth of bitcoin as whenever there is a pump in the value of bitcoin we have witnessed green days for altcoins too but how long will altcoins be dependent on bitcoin? Do you think altcoin can do it alone and have it's own pump and dump without being dependent on bitcoin?
That won't happen because Altcoin is a child of bitcoin or a complement to cryptocurrency. Altcoin will always follow the movements of bitcoin prices although some altcoins can increase its value, that is because there is a pump against Altcoin itself.
