you should not mine bitcoin as a newbie to be a miner, unless your power supply is cheap enough (or somewhere near you can get renewable energy). you should use (spare is better) GPU or called graphic card to activate mining, but few of the coins are currently profitable (bitcoin is normally losing); in this point i would recommend merged mining in some of the pool, they are possibly better on profit.
Yes, I agree with lottery248 that it would not ne better if as a newbie you would do mining because you might not know what is the needed equipments and it really costly to mine some bitcoins and right now I think mining some altcoins because it is more profitable if you mine some of it.
If you are looking for profit might be better to buy and sell coins. Ive made more doing that as a beginner.
Definitely, trading is the very basic to learn if you are newbie in the world of crypto because you find a way to learn some concepts that will be helpful to you when you go along the process.
