Thanks,
I guess I'd pretty much ruled out mining bitcoin/litecoin because of the difficulty / the small amount I would expect to mine with my setup.
I was more thinking about mining a couple of "new" / more unknown alt coins, and take a gamble on that they in the future may be worth something on an exchange.
I'm not sure if it's the best strategy from a profit perspective though
In terms of "worthwhile", I was thinking about coins where you still have a possibility to solo/pool mine a reasonable share (even if the coins are worth next to nothing) withouth investing in ASICs.
I've been looking at the charts over at
http://coinchoose.com/, but I struggle to see how I can calculate when I can expect to find a block solo mining by combining the difficulty/network hashrate / my hashrate. Anyone know how to do this ?
