I notice you mentioned you cannot mine. If you want to try a coin that you can "mine" (actually we call it minting) on a regular computer without high energy costs might I suggest MINT?
You can mint more coins simply by holding coins in your wallet for 20 days. It's equal to 20% interest compounding for the first year if you don't never move your coins from your wallet. Or you can buy stuff in over 30 different merchant sites that accept MINT as well as trade it on an exchange or use it to gamble on one of the sites that accepts MINT. I think it's a pretty good "investment" to fool around with, mainly because I like the community and we are trying to develop the full potential of the coin.

And since you are a new, welcome, but remember do your due diligence and be careful there are a lot of crafty tricksters out there.
