Is it worth mining Litecoins and then exchange them for Bitcoins (because I am not sure if there will be space for more crypto currencies in the future)?
I can get about 25k hash/sec by CPU mining on my laptop, so this turns in something about 0.1 LTC per day which is 0.06 BTC per month (current exchange rate is 1:50). Does my approach make any sense or is there nowadays even any way to mine with everage/above average hardware?
