Right now:
I'm having a regular income from my job (~1.800€/month) and some extra one (not regular) from fixing some stuff for friends' friends, people I know, etc. (let's say 200€/month).
My contract lasts 7 months (5 from now on) and I will not be working here after that.
I started working 2 months ago and had no savings untill then.
My monthly costs are very low as I live with my parents (about 150€/month) but would like to change this in the near future.
Future plans:
When I'm done with my current job, I'm planning on starting my own company with a friend, where we will need to spend, at first, about 8.000€ so I would like to make as much money as possible before that happens so the company can be alive for some months in case we can't make enough off it.
A bunch of small investments or a few big ones?
So, here is the main question: how should I invest my current job earnings (should I even risk them?) during the next 5 months?
So far, I've been buying some domains and setting up some 'lowcost' webpages with advertisement on them as I have hosting access and only need to spend money on buying domains (~8€/year). The problem here is that, even if I make money, I wouldn't be doing much from every investment, but a low amount from all of them.
And, over anything, I have to keep in mind that I'll need ~4.000€ for the company's first investment.
