Yea, hodling Bitcoin is a long term goal. You can as well trade market to make money so you can add more to your hodlings. As for op, to be sincere both mining and trading requires you spend a lot of money but on the long run, you can make a lot of profit from either. The only difference is that trading comes with risk, while mining comes with cost.

 Either ways you need to spend a lot of money before you can become profitable from them. Just like others have said, mining cost more as you need to buy some tools, pay for electricity cost and also you won't be profitable running a solo miner. Trading on the other hand is risky but once you master your strategy, you make good Money from the market.
