The way I see it, it still is more profitable to mine BTC with GPU rather than YAC so what is the point, really ?
I noticed that too. Even with 10x more hashing power its still about half as profitable as btc mining in my case.
I see quite the opposite. Even with the very low conversion rate of ~0.000174/BTC. A 10x7950 mining rig will do roughly 0.25 - 0.32 BTC per day (1500-1800 YAC/day). With the current Bitcoin difficulty of 19339258 the equivalent is ~0.145 BTC/day. The YAC gpu miner also draws 400-500 watts less (I assume because it's "not yet optimized"). This is only true of course if you (can) sell your YAC's everyday. If the exchange rate increases a bit, you get an equivalent increase in BTC/day. However, with a market cap is only ~$69K (
http://coinmarketcap.com/) it is heavily susceptible to heavy dumping, which will drive the price too low to be profitable (at least for the short term). The effect of the pending N increase (June 25th) is also a factor to consider as well as the subsequent difficulty adjustment.
