Well I'm unemployed so... how steep is the learning curve for trading? Can you suggest reliable sites on where to learn about this? And how much bitcoin would I need as startup?
Well as long as you understand the difference between higher and lower numbers in base-10, you have all the skills you need

Buy low, sell higher, repeat.
Just don't buy in for more than you can spare. Don't put the rent/mortgage money in there.
I started with half a bitcoin. Now I'm all the way up to 8.
