Bitcoin is regaining dominance is a positive sign for the entire industry sooner we can expect altcoins previous values come up and cryptocurrency look positive bull rally about to happen
Many companies issue cryptocurrency with the aim of mastering trade so that profits increase. However, the market always responds by comparing bitcoin, because bitcoin is converted to US dollars. It's very difficult for altcoin to shift the dominance of bitcoin, because the spirit of cryptocurrency is bitcoin. Without bitcoin, cryptocurrency trading is very small and unpopular.
Bitcoin is the basis of the price of the crypto market, so when bitcoin is down the market is down too. I am not sure if there will be coins that can beat what bitcoin already achieved now.
