766  Economy / Service Announcements / [ANN] Coinut.com - The only Bitcoin Options Exchange [beta] on: October 13, 2014, 11:58:46 AM
We just launched Coinut (https://coinut.com), the only place where you can trade bitcoin options. Predicting the market direction is usually difficult, while predicting the volatility is relatively easier because the volatility after high volatility is usually still high, but the trend of BTC/USD after a slump is usually...unclear. Through options, you can make profit from volatility trading with confidence. This is just one advantage of trading options, and the following gives you a complete list

  • By trading volatility, you can make profit no matter which direction the price is going in
  • You can also make profit by predicting the market direction
  • Your maximum possible loss/profit is determined at the very beginning so you don't need to worry after you buy an option
  • High leverage without default risk

What are options?
Options are a simple way to trade price fluctuations. By trading options, you can profit in both bearish and bullish markets. For example, if you believe the price of BTCUSD will go above 500 by next Friday, you can buy a BTCUSD call option (or sell a put option) which has the strike price equal to 500 and expires on next Friday. If you hold the option and if the price is indeed above 500 at the end of next Friday, you win, otherwise you lose. Instead of holding it, you can also sell the option to others before it expires.

The options in our platform are bitcoin settled. No matter you are are a seller or a buyer, all you need is bitcoin.


How to trade when I cannot predict BTC's direction?
You can bet on bitcoin's price direction if you are sure about it. But in most cases, we don't know the direction. Instead of betting on the direction, via options, you can trade its volatility, which is generally easier to predict. For example, if BTC/USD is now 400, and you know the volatility will be high, you can simultaneously buy a CALL option with strike price equal to 420 and a PUT option 380. Then you will be able to make profit no matter which direction BTC/USD goes in, because if it goes above 420, the CALL option will win, and if the price goes below 380, the PUT option will win. For more detailed information about trading options, please check https://coinut.com/how-to-trade.


How do you ensure the safety of my money
This is a critical question, and thus the answer will be a bit long.
First, we think hot wallets cannot be secure as many sites like Mt.Gox were hacked in the past no matter how hard they tried to secure their sites. So, we do not use hot wallets. Instead, we store all your Bitcoins in an offline computer (cold-storage) that cannot be accessed through the Internet, and the online wallet is only for monitoring purpose and cannot be used for withdrawals. The offline computer's hard disk and the wallet are all encrypted so even if some people get physical access to the offline computer, they still cannot access the wallet. Also, withdrawal requests are manually checked before they are processed.

Second, we believe transparency is very important. Therefore we adopted the proof of reserve audit approach described in this article. It generates verifiable audit results and has been adopted by a few big name exchanges such as Bitstamp and Bitfinex. We move this idea one step further. Instead of relying on a third party to verify that we have more Bitcoins than users' total balance, we directly show how much Bitcoin reserves we have and how much the total user balance is, and we do this weekly instead of quarterly or yearly. This removes the necessity of the third party, which users may not trust, and also provide much better transparency to the users.

Third, when we copy the double checked unsigned transactions from the online computer to the offline computer to sign, we do not use USB drives, as the online computer may be infected with virus (although this is unlikely as both the offline and online computers are based on Linux. The offline computer is dedicated for signing transactions after the Linux system was installed, so there shouldn't be any virus). We convert the unsigned transactions to a QR code and show it on the online computer's screen, and then we use the camera of the offline computer to scan it. After signing the transactions, we display the QR code on the offline computer and use the online computer's camera to scan the signed transactions and propagate them into the Bitcoin network.

Forth, our system is deployed on the always update-to-date Linux operating system, and we follow the best practices of Linux server management. Our system is deliberately programmed in a secure fashion. Our databases are backed up every day, and all important information is logged and backed up as well.
