I can still see this as a possibility even though in the past months with bitcoin going up and altcoins not following up, it already changed now because some of the altcoins are increasing its price. Even though the year is not yet near to end, I think they will still keep on improving and will follow up to bitcoin. Good coins such as Ethereum and LTC will blow up if the increase continues.
The altcoin price in my opinion will continue to rise, because it follows a positive trend created by bitcoin, even though the rate of increase is not as big as bitcoin. Because altcoin for investors is an alternative investment when the price of bitcoin falls.
Altcoin that is traded today is Ethereum, Litecoin, BNB or Dash, and it continues to provide a good level of profit. Investors prefer bitcoin because of the higher rate of price increase, but that does not mean ignoring altcoins.
