yes of course. i think Each coin is used for a different market or sector. It will create a true market 
we need those altcoin for us to find which is better and helpful,there lots of new project that offers almost same functions,and most of them are copycats ..but if future the real one will come out strong and make t difference above them all,not just those offering virtual servie but those general service too.i cant wait to see the future in which everything is a button away.
