I believe that buying bitcoin is a better option than mining it. You can buy bitcoin with an amount you can afford as there is no limit to how much you must put at risk. But when it comes to mining bitcoin, you will have to buy hardware with a certain configuration that comes with a high price tag. On the top of that, there is no guarantee if you will be able to mine bitcoin successfully or not. So, better go for a safer option which I think is trading.
