If you posted, I have 0.5 extra btc that Im willing to lose. Then I would help you find somewhere to gamble it and maybe become a lucky winner. Any investment has the potential to take all of your btc away.
A sound investment for someone without much money is to hold what you have and add any extra fiat to that slowly as you earn it through a regular job. Take all the money that you would rot your teeth with every month (buying sweets and soft drinks) and add that to your btc holdings. Pick a thing that you spend money on every month that you dont really need and buy bitcoin instead (I suggest dumping your girlfriend, you wouldnt believe how much money you can save with that one alone). Bitcoin has the potential to increase by 100%, 200%, 300% or more in a short time. Thats the least risky investment you will find around here.
I like the line "I suggest dumping your girlfriend, you wouldnt believe how much money you can save with that one alone". That's one of the best advices one can have if he want's to save money
