I am curious, how does wirex compare to GDAX? I am very happy with the low cost and free transfers between coinbase https://www.coinbase.com/join/5a74f1cabafd0b018d211616 and GDAX. That way, you can get pretty much instant , real-time prices and instant money transfers with almost no fees. If you haven't tried it yet you can try with my link and get $10 in free BTC.
