I don't trade bitcoin, so I don't have any experience with it. But, at the time of writing this, I saw BTCUSD on the market watch window of the mt4, but it is in grey, which means I cannot open a deal at the moment. Maybe there is the trading hours or so. I suggest you check the bitcoin trading hours, if there is anything of such. Or better still ask the broker. Also, the bitcoin deposit and withdraw option is easy to spot on the deposit page. It is available, I have used it twice.
