Something interesting I've observed lately is an increased interest/awareness in altcoins.
Our forum has been seeing exponential growth and one can look also in the newbie section here and see more and more newbies discussing altcoins. It wasn't that long ago I was scolded by a moderator that newbies didn't need to hear about altcoins and not to talk about such things as it might confuse them. Now it seems the tide is turning and that the altcoins are gaining wider acceptance both in the mainstream and here on this forum.
Over the coming months, I think we'll start to see some of the stronger altcoins begin rising up to challenge Bitcoin then perhaps overtaking the top spot maybe even as early as 2014.
