I think listing figures like hundreds of bitcoins could easily mislead or confuse people. Probably should be listed in fiat as well for the reasons I mentioned before.
Mentioning amounts in dollars just doesn't sound right on a Bitcoin forum. May I suggest using
an image, where you set the amount in dollars, and it shows Bitcoins. Example: $1000=

.
The down side is that it gives weird looking amounts, but it's updated on each reload.
But that isn't an accurate representation either especially if you never held that amount in bitcoin. Not everything has to be denominated in bitcoin either, especially when the value fluctuates so much and that's why a fiat value gives a much better and accurate representation and why it should be represented here. If you held £10k in bitcoins then it's the £10k that is the pertinent figure and that's what others should be judging you on.
