Look at
http://coinmarketcap.com/Lots of money pouring into alts due to this ridiculous blocksize debate.
Needs to get fixed soon.
Nope..
It's just 'Alt Coin' season. Traders on site I that I subscribe to been going on about it for weeks, and well in advance of them all taking off.....I personally never jumped at the chance to start doubling and then quadrupling my BTC though....I only like to fight battles that I am going to lose. I have stuck with Short Stop Running, Manipulated by the Market Makers Bitcoin.
I have no idea why the post Christmas/early new year period is Alt Coins season, but it is....some theoeries about of 'Little Johnny Geeklord' just having been given a $500 bung for his Christmas, and gets a bright idea about how to make a mint with it, thus rampers start pumping Alts, which attracts Little Johnny and others like him to pile in.....
.....quite insidious really.....taking advantage of the naive and stupid, but then that is markets in general.
