I am still quite new to the mining aspect of crypto-coins and very surprised that there are so many alternatives to Bitcoin which I tried to mine ages ago but didn't get it going.
But now I have got Litecoin mining operating successfully. I only have an ordinary workstation and use the GPU running Cudaminer. I only achieve a hash rate of 175k so this is hardly economic.
I have traded BTC and LTC using a trading programme called Plus500.
I have traded normal foreign currencies for years and enjoy it as a challenge, it hasn't made me rich or poor.
Good Mining. May your hashrates be high
