I've recently discovered DvoraKoin,
https://bitcointalksearch.org/topic/anndvk-dvorakoin-multi-algo-shascryptgroestl-now-on-4-exchanges-613854 Which has multiple algorithms and a skewed block rewards system.
It had a big spike on the weekend but has since lost a bit of interest, but after modifying bitcoin and litecoin's parameters on coinwarz, I've noticed that even at its current weak price it's still waaay more profitable than LTC or BTC! Mining with 1000khs scrypt will net you about $3.50 per day! That's almost 3x the profitability of LTC!
BTC is the same! 100gh/s mining the SHA-256 section of DVK will have you earning $8.00 per day, as opposed to bitcoin's $3
The other featured algorithm, Groestl, is again the same story. (Groestl is in my opinion better than X11 and Scrypt)
10mh/s on Groestl will earn you about $2 per day, while GroestlCoin (The Groestl flagship) will be more like $1 per day.
Jump on board now! This coin seems to have died off a bit, but once a few miners realise its profitability I'm sure the price will go straight back up! (It almost hit 0.001
BTC on the weekend!)
