Not because of the gateway... but USD liquidity is horrible on bitcoin-24. SO its only good for trading EUR/BTC.
Is bitcoin-24 for real? They claim no fees for trades, no fees for withdrawing or depositing BTC and only 1.24 EUR for depositing for withdrawing BTC.
I don't see how they can be paying their running costs.
I have no idea how. I use them and they have the highest EUR volume of all exchanges.
