How to get started with a small investment and no experience

I would like to begin trading with automated systems or robots.

Because I don’t know about trading, I think it is better to find a reliable robot and let it trade for me.

Is it sufficient to have an initial capital of $2-3k to start trading? (if I am correct too small budgets have a higher risk, so I am wondering if these amounts are a lot riskier compared to for instance $10k).

Which broker would be better to get started? I have seen about 24option which claims to offer “1 year risk free”. Would this be a good option?

What do they actually mean by “1 year risk free”. Does it actually mean one cannot loose money?

Thanks for your guidance,

Ernest
