While being a poor you should not take for investments because investments comes with risk so there is no guarantee that you will get guaranteed returns, becoming rich may not happen in a week or month or even in years it may take few decades for a poor to become rich and yes there are some exceptions but those are very rare.
Save money then start investing!
