A lot of this coins are from the same persons and multipools.
Look, there are a lot miner, and they bought expensive hardware. With Bitcoin they won´t have apositive ROI anymore. So they create coins with a high reward and short mining times. Then they mine it like hell and dump them on the exchanges. And then they create the next one. Almost all of them are exactly the same.
If you go through the announcement section, you can ignore the starter of the topic, then you won´t see the threads anymore.
So if you see an OP with blockreward, etc and algorithms like scrypt, x13, etc etc then just ignore.
So very true.
What gives these coins momentum are the miners who think they'll get a free lunch. I guess there is such thing after all...
