I don't think there's a definitive answer to this question. Trading can lead to losses and requires a lot of resources. Mining will bring BTC, but it requires investments into equipment, as well as further expenses with electricity bills and equipment management. Trading requires luck and/or special skills, whereas mining is more straightforward. But the simplest thing is to just buy BTC and hodl long-term. You don't need to invest a lot of time or resources, you just need to be patient and believe in BTC's long-term growth. There are risks, of course, but still.
