By 2020 virtual currency will be more popular and so altcoins too will be reaching a very big user base than the present. The volume too will be increasing very big for most of the altcoins. Hope bitcoin will be serving as the head as the upcoming halving by the year makes a added demand to bitcoin because of supply reduction.
Very much agreed! Within the matter of years I see the demand and popularity of alt coins as well as bitcoins growing, especially with the endorsements we are now seeing. I feel that many ICO's are trying to make a name for themselves which only increases opportunities for investors!
