Interesting site.
How do you see who has open bids/asks for the options? I don't see any volume.
You might look at cutting back to bi weekly expiration dates or monthly until volume shows up.
On the Trade screen you can see the best bid/ask for each option. Typically option chains don't show open bids/asks, but do show
open interest.
There is no volume yet. I think I have to explain the opportunities the site presents first. Bitcoin is still a relatively small community. You're right it may be a good idea to limit expiration dates. For example, a 2 month max contract term may be better than 1 year and would also help limit insufficient escrow due to volatility as I'll explain below.
I'm still wondering how you are going to handle counter-party risk ?
This is the trickiest thing to solve, even in the real world
It's even harder due to bitcoin favoring anonymity.
First we backed options with bitcoins, but I thought that was too burdensome. A contract for difference model is far more flexible. For example, @Brunic says he is currently mining the 300 coins he will sell in the future, so he couldn't put them up for collateral beforehand anyway.
In our Beta feedback thread someone suggested using a formula to calculate escrow, so that's the direction we went. However, I'm now thinking that may be too complex and inadequate for coverage. I'm thinking to simply require escrow to cover a 50% price move.
That gives traders more solid payment assurance. They can feel safe buying with the potential to make up to a 50% difference in price.
In the example above it would mean, for example, putting up $6.50 x 50% = $3.25 then multiplied by 300 coins = $975 into escrow.
That's a lot more burdensome on the option writer, but only half as burdensome as putting up the coins directly. And it gives plenty of upside room to speculators. The price could move to $9.75 and they would know they would be paid.
I for one absolutely LOVE what you are trying to do. Being a finance geek, I would love the opportunity to sell call options against my future production.
Clearly the biggest issue you are going to face is generating sufficient volume in the contracts. I doubt you would be willing to be the counterparty to thousands of contracts miners will sell short?
Thanks!
No us being a counterparty wouldn't be prudent, but there may be good interest in the speculation thread. It's chicken and egg, though, first the options have to be written before people can decide whether or not to speculate on them
