I have championed the two digits to the right of the decimal for bitcoin for a while now. I also believe the name bits is perfect. "You use bits on the bitcoin network."
Personally I think everywhere bitcoin is used it should be displayed like this (regardless of whether it is called bits or not):
2.34
89.23
93821.49
54.00
We should really consider this for GoldCoin as well. Adoption is FAR easier when the currency looks like money that's currently being used. As much as we can, we should try to get away from increments with long decimals: .00002345.
This is not pressing for GoldCoin now but we should consider it in the future.
