@tonypeacock. Thanks to you I finally got some bitcoin to bitshares and tried trading it. After 100 trades my 3.1 bicoins seemed to be worth only 2.8 bitcoins. I will investigate why I had this slippage, because I thought my trades were profitable.

However I have a question which maybe you can help.

I see the there is open.btc and bit.btc. They are both supposed to be equal to the price of btc, but they have different prices. It seems that open.btc is about 7% cheaper than bit.btc. What is the difference and should I switch from one to the other?
