Mining is a passive type of earning Bitcoin and you'll just have to setup your machine and devices to operate 24 hours 7 days a week and it will continue to get satoshis into ur wallet.
But, I believe if you're a skilled trader then you could earn higher money than mining. But trading requires more time to monitor the market value in order to hit buy and sell if the price are getting low or high.
For me if you have other business and other important life activities then you'll better go for Bitcoin Mining, otherwise, Investing and trading will offer you higher earnings and return of investments.
