The altcoin market is growing everyday and it is just a start of the growth of this market in next 2-3 years we see a big boom in this market and many altcoins makes many millionaires in future.
i think not if there's always new alts that keep born and born, and not just that, some new alts without a clear roadmap and whitepaper but have a good price at starts is only good for beginning while for futures maybe it doesn't have any.
more new upcoming ICO is keep started everyday, that's why more alts growth will be very slowly
