Get an account on there, get USD in somehow (either wire in funds the old-fashioned way or send in BTC and sell swaps/futures/options), and then you can sell puts at any strike/date that you want, as long as you have the USD collateral to lock up to maintain them.

So if e.g., you wanted to sell 100 contracts (1 btc worth) of $40k puts for June 2021, you'd be "locking up" $40k until you exit that position, which would be June at the latest. You could also unlock some or all of that money early by buying back some of those contracts on the market, possibly at a profit or loss depending on how things move. Or you could ride it out until expiration and hope BTC is trading above $40k at the end of June.

Does that make sense?
