I released a BTC/SLD exchange called solidcoin24 (
www.solidcoin24.com).
I tried to make the service a bit more newbie-friendly and easier to use for people who have no trading experience yet (e.g. I added confirmations and explanations to most trading actions). I hope this will help get Solidcoin more popular.
Also, the trading completition approach is slightly different. While most exchanges require you to give a buy-target and an upper limit for what you want to spend, my exchange requires you to give a lower limit for the amount you want to get and a fixed spend amount.
Example:
You have 10 BTC and want as many SLC as possible.
In most exchanges you would have to chose a certain exchange rate and if you are lucky, the order is completed and you have some BTC left. Then, you would place a new order to spend the remaining BTC and repeat over and over until you spent all your BTC.
At solidcoin24.com you can place an offer like this:
I offer: 10 BTC, I demand: at least 500 SLC
solidcoin24 will then try to buy as many SLC as possible, until all 10 BTC are spent.
Another feature are 'atomic' trades:
They are invisible, indivisible and will only be completed if they can be completed at once. So they don't influence the market until the order is completed. They also don't appear in the ask/buy list (that's why they're invisible).
I introduced this feature because I wanted to avoid a certain trading behaviour: Some people, including me, don't want to place an order and leave it there for a longer time.
Example:
I want to sell my 5,000 SLC for a nice amount of BTC, but I can wait.
If I place an order (5,000 SLC is quite much currently, comparable to, say, 10,000 BTC in terms of market influence) other people will see a huge sell wall. What they think is "Oh no, there's a huge sell wall, the price won't go up anytime soon". This is exactly what you want to avoid because the exchange rate is likely to go down or at least unlikely reach your rate. Solution: invisible atomic trades.
Everybody who signs up will get a free Solidcoin (that's 0.015 BTC) to toy with. (50 users have been reached)
So please try it out and tell me what you think
