again, I'm one of those people selling GBP, and I've sold about 400GBP in just a few days.
It get's sold, I think that's why nobody lowers their offers.
But indeed, that is more of a problem. The only think that the government can do is that when someone lower their offers to 0.026, buy it, and resell at 0.027.
This will eventually mean profit for the government, but you need to have a growing economy and a certain amount of gold you don't need in the near future.
(I guess that's what they are doing now, and that's why there are no 0.026 offers)
Also, the brits are used to following rules and waiting for stuff, I guess it's in your nature.
