The basic concept of hedging is that you pay a modest amount now to avoid a catastrophic result later. So the question is what a catastrophic result might be in this case. You have bitcoin or a promise of bitcoin in the future. You want some other currency or goods. It would be catastrophic for the value of bitcoin to fall.
A bitcoin/goods hedge may be hard to find, because I'm not sure that the goods market in bitcoin is well enough developed to have real futures. In theory though, you could buy an option allowing you to buy some good for a particular amount of bitcoin. If the value of bitcoin goes down, you exercise your option (or sell the option and use the proceeds to buy normally). If the value goes up, you let the option expire and buy normally.
You already know about currency futures. You want to hedge against a fall in bitcoin prices. You buy a put option where you put your bitcoin in exchange for some other currency (e.g. US dollars or whatever works best for you). With the put option, you are guaranteed a certain price for your bitcoin. If bitcoin falls you exercise the option (or sell the now profitable option to someone else and use the proceeds). If bitcoin rises, you let the option expire and sell your bitcoin normally.
This would be a put option in terms of the other currency. From the bitcoin perspective, it could be considered a call option. The important part is that it guarantees to you that if you exercise the option that you will get a certain amount of the other currency for your bitcoin. You may have to read the option carefully so that you get the right option with that property. Don't get too caught up in the name, which depends on perspective. It's the property that is important.
You may wonder if call options are valuable. As a hedge, no. But if you need a certain amount of the other currency (not bitcoin), you might be willing to sell a call option. You can then use the proceeds from that sale to purchase your put option. This surrenders your potential profits, but the purchase of the put avoids potential losses.
As others have noted, it would make more sense to sell the bitcoin now than to go through this hedging process. This only makes sense if you can't sell now (e.g. you haven't been paid yet). You should realize though that if you are promised bitcoin, you also have the risk that you won't get the promised bitcoin. If you sell a call option in that case, you could find yourself forced to buy bitcoin to service the option.
Buying the put is less dangerous. At worst, you don't get the bitcoin and can't exercise the option. You have to let the option expire. Even in that case though, you might sell the option and make money that way. Buying an option is inherently safer in terms of exposure, as you choose whether to exercise. You can always choose no.
Selling is more dangerous as the other side can choose whether to exercise and will tend to do so when it is disadvantageous to you. If the option is covered because you already have the thing that you purchase, that's what makes it safe. But make sure that you really do have it, not just the promise of it. Or accept the risk that comes with not getting it.
