Im guessing you meant buy more option equivalent to share price so if it goes bust you loose same amount.

This is true however by doing this you have MUCH more exposure and if SP goes above strike its like owning much more stock rather than the 1 stock. We call this delta in finance.

If you load up on option instead of stock and you bought the same dollar value then you would high a much higher delta which means you position would be much more sensitive to price movements than just the stock.

Options also go up when the underlying asset have a lot of volatility, while the opposite is true for shares. We call this Vega.

There are many other greek letters but it gets complicated. If you are interested in options best bet for a beginner is to concentrate on your delta and vega positions. And maybe gamma (which is kinda a delta of the delta) but it is a hard concept to understand and benefits from gapping which this stock tends to have a lot of.
