Re: Official Newbie BitInstant Support Thread (Active Customer Support)
Always send cash to the exchange then you are in control of the price. 
That is the best advice someone could give. I undersign. You get then exact amounts and don't stay complaining about discrepant exchange rates at time of processing/conversion.
In my case, I had cash deposited to gox through BI. At the time, BTC was $85. I was buying ahead of what I knew was an imminent rise in BTC value. We all know how it skyrocketed a day or two later...
