This is a X-post from here but I guess it is very interesting for all the lurkers of this board, with certainty more then for those in its "correct" place.
So, I just read about them on
reddit:
http://www.bit4x.com/Forex in Bitcoins!Bit4X enables you to trade over 30 currency pairs on a pro grade platform in Bitcoins, including Gold and Silver!
They use the popular Forex program
Meta Trader 4How does it work?Trading takes place on a well known and widely used trading platform: MetaTrader 4. Your balance on the platform is denominated in Bitcoin and so are your payouts.
Current Bitcoin exchange rates won't affect your trading limits. With the minimum deposit for opening a Live account, 100 BTC and 1:10 leverage you can trade up to 0.01 lot. With the same deposit and 1:100 leverage you can trade up to 0.1 lot and so on. We offer leverage ranging from 1:1 to 1:1000, but we strongly recommend below 1:20 for novice traders. You can change the leverage of your account at any time or open several accounts, if you are in need of more than one leverage option.
Are my Bitcoins safe?Yes, your Bitcoin deposits are never converted into fiat or any other form and are always kept safe in encrypted cold storage by kakobrekla, a well known member of Bitcoin OTC.
Bitcoins are volatile, can you guarantee my payouts if Bitcoins rise or fall in value?Yes, our broker VenetFX holds extra Bitcoin reserves, twice the sum of all clients deposits at all times. Just in case that won't be enough, the broker will acquire more Bitcoins on the market.
1: Does that mean I can trade my bitcoins with 1:1000!! leverage??
2: Or does it mean that we can fund our accounts with bitcoins but are only allowed to trade on traditional currencies with that 1:1000 leverage?
-edit-
This article indicates (thx Enky1974), that no currency pairs involving BTC are traded, only traditional currency pairs, like USD/EUR or XAU/USD, while your account balance can be funded with bitcoin.
