Congratulations on being the first to launch this service, I've been waiting for this day. It seems a little "too good to be true" which, in combination with the bitcoinica fiasco, leaves me skeptical.
I'd like to know where you hedge the gold positions, to have more confidence bitdaytrade isn't a bucket shop (with bitcoinica it was known they hedged at MtGox).
Also, why no MtGox codes for deposits? You claim to sell the BTC on mtgox anyway..
We have methods in place to watch for those circumstances and take appropriate action, i.e. Buy Bitcoin if price suddenly spikes up and use USD reserves to back up gold trading. We are also planning to add Bitcoin as a traded commodity itself shortly, just like Bitcoinica.
This seems like a disaster waiting to happen. If you buy bitcoin when price suddenly spikes, you'll have losses (bucket shop betting against the customers).
I like that I can stay long in BTC and open a gold position. Decreasing my gold position if btc falls, so that i take losses if its a losing position, is the right way to do it. Good job with that.
But if you're hedging/scaling the gold position then there should be no need to sell the deposited BTC (and again, you can't sell it without betting against the customer).
I deposited a few BTC, but I would've been able to short gold earlier if I didn't have to wait for the confirmations. I missed the big move down.. going to wait for a bounce up now.
