Your profitability is pegged against litecoin - Is it the most profitable single coin out there?
I did a quick compare to Doge here :
http://bitinfocharts.com/comparison/miningtobtc-ltc-doge.html because Doge was brought up earlier in discussion. Seems that as Doge seems to be a bit stronger than LiteCoin it may be a better benchmark for comparison.
I realize you can't cater to every coin, but perhaps put a couple other 'big' ones on there and it could help sell your site better?
Doge is a joke coin. Because of auto-switching pools raping the high-value blocks, the real profit from mining doge is much smaller then the projected income. Suffice to say, if you want to mine scrypt, you compare against the stable, highest hashrate, and non-retarded standard LTC.
I also agree with you on this. Comparing to Doge coin is not a good idea. Even the creators of Doge coin were surprised with the value seeing as they made it to be a novelty/joke coin, much like Coinye was going to be before its demise.
That being said, it can a very profitable coin to mine assuming the other pools are not also mining it. I always get flack for saying this, but what makes Doge coin's price swing so bad is when huge multipools like MC or HC switch to it then have to dump the massive, massive amount of coins, it drives the price down. Once they stop, people rise the price again to make a killing when this cycle happens again. How do I know? I do this a lot along with some other large miner's I know. There is good money to be made riding the Doge waves every night when MC and HC does their exchange.
