I am currently mining (and buying) LTC and occasionally I mine some BQC (which I sell for BTC/LTC). So I am not trying to pump primecoin or XRP or whatever
As for KNCMiner, I think that if they are able to deliver the BTC miners in September they will instantly have a very good reputation.
In this article they are being interviewed :
http://www.coindesk.com/a-look-inside-kncminer/ They want to start with a reprogrammable FPGA Scrypt miner, so you can mine not just LTC with it but also other Scrypt coins.
The company is planning an FPGA targeting the Scrypt-based altcurrency market, dominated by Litecoin, but with many other competitors.
Users will be able to visit the KnCMiner website and download software to reprogram FPGA chips to mine any new coin that emerges as a contender, he promises. “
That means that we can sell a $3000-$4000 product that returns your investment,” he says, but adds that it must be more functional than Mars.
“It needs memory channels, the ability to be reprogrammed, and probably its own web interface.”
