Options on Bitcoin

I would like to speculate on bitcoin by using Call and Put options.

I have already tried on Huobi but I think the fees are very high. I don't have so much experience but I see a spread of 500usd on every position I have tried. I am just spending some dollars to understand the logic and the tools behind it.

Let me know what you use and what is the best platform for you. I would like to know what is a good fee for make trade.

I already know thinghs about self custody and risk management

Thanks a lot to everyone for your time and your answers
