I see for the first time a miner for mining on a processor using the x16r algorithm. This algorithm combines 16 different hash functions that are not always efficiently executed on the processor. Is there a profit from mining on the processor, for example, for Ravencoin?
For Ravencoin, not even by a long shot.
It's not only GPU mine-able, but also FPGAs are being programmed to mine it... though how successful they've been so far I can't tell.
I think there was still an algo with only CPU mining support, something that sounds Japanese-like... I can't remember the name but it had very low liquidity and profitability so I didn't bother.
