I'm trying some investments at a known Crypto-Exchhange at bleutrade.com
(There are other Crypto-Coin Exchanges out there like bitfinex, okcoin & btc-e)
Buy Low, Sell High. The graphs are very helpful with visualising potential. Even Investing in BLEUTRADE SHARE pays back BTC! They even have a DOGECOIN market which investing in DOGECOIN pays back in DOGECOIN too. Investing in Alt-Coins may be risky but consider their value is competing with Bitcoin. More information on any BTC/Alt-Coin can be found right on this Forum! Read up!

Buy Alt-Coin @ 0.00006156 BTC
Alt-Coin Value goes up
Sell Alt-Coin @ 0.00007345 BTC
Invest a little Bitcoin (Could try $1USD worth) and see where it goes since the potential of Bitcoin was about ~$1000USD at one point. I would suggest to save most of your Bitcoin for if and when you need it.
Paying any service in $USD/EURO(Any physical Currency) and only returning in BTC without having the BTC being able to go back to $USD/EURO(Any physical Currency) is not really a great service.
Buying Milk at the Store... Do you accept BTC? There are more places starting to accept BTC these days.
If you plan to invest in BTC, don't break your bank over it.
If you read any information, use at own risk.
