I would be more comfortable with 300b to buy and 225b to sell. Just me though.. 2.5t to sell is crazy and the majority of KaW doesn't have 3t sitting around.
No Support. Yet. Give it about a year first, when the gold inflation is higher. Then i shall support.
On a kindof related note....when things sell for 75% of the purchase price and are used only for banking and selling (ie. bars).....why make them values of 3 instead of 4? It would be so much easier to do the math if silver bars were 4 billion instead of 3 because then the sale price would be 3b and not 2.25b. It's a small thing, 2.25 isn't that hard to run the math, but earlier today I was trying to figure out what 1750 bars would sell for so I knew what I needed for next upgrade. If they sold for 3 (ie. a whole number instead of a partial number), it would just seem to make a bit more common sense and would be simpler to figure values in your head.
