You can easily earn BTC through mining. you don't have to do anything and you will earn BTC as long as you have your right equipment or by trading but make sure you watch tutorials and know how trading works like candlesticks.
Mining today isn't worth to earn and invest. Because of the halving difficulty gets higher and you can't expect more.
Mining equipment are also expensive and the return won't be that worth for this way of earning these days.
I will suggest that invest into bitcoin or trading by simply buying bitcoin and just hold it forever.
