How should I hold my cube?

I am currently sub 30 but I noticed when watching some You Tubers that they all hold their cubes with their thumbs on the front. I found I can go faster with my right thumb on the bottom and my left thumb in front. Should I start learning to cube with both thumbs on the front?

I think you just go with what feels comfortable to you. Everyone has their own style and at your stage, how you hold the cube will likely have little effect on your times. Play around with different grips and see what feels best to you.
