I see things have changed on the site

Is a BTC call a call now Like when you buy a call you're betting the price of BTC goes up?

Is a BTC put a put now Like when you buy a put you're are betting the price of BTC to go down?

I assume these prices are in USD now?

Assuming above
Can you go over the exercising of a put option if I was a put buyer that wanted to exercise the put I bought.

If I am paid in BTC as a put buyer who has exercised my put I have a problem in my mind of even making a trade. For one I will be paid in BTC which I think has no value. If the value of BTC is cut in half before I can trade it for cash I could still lose money even though I was right.
