The growth of the market and the rest of the altcoins mainly depends on the growth of Bitcoin, so I do not think that any coin will grow faster than Bitcoin for a long time.
do not see any other coins moving faster than bitcoin, because to this day I see other coins moving with bitcoin. So what I see to this day is when bitcoin prices go down then the other coins are down too, and vice versa when bitcoin prices go up the other coins go up. This proves that bitcoin is still the best and number one compared to other coins, as they move to the rhythm of bitcoin.
