More risk, but much more reward.
Considering how risky bitcoin is already why would you want to add to that?
That's the point. With a higher risk on initial investment, you have a greater potential reward. Say you buy $8k worth of BTC for $14 and sell for $17. You get much more out of that than buying $100 of BTC.
I also understand where you're coming from: the safer standpoint, which is where I stand too, so don't take this as me bashing you
