I'm interested in mining, and looking for small coins, which I can mine and get big reward for mined block.
Got it. I think, this stratedy is so risky, because you won't now, what will happen with coin, and will you able to sell it.
Risky, but reward is also big - with 5-10 ASIC's you can have big reward for blocks in this type of coins - because small count of people mine it.
