Why the surcharge increase on the ฿20 bill? Especially with bitcoins having appreciated since they were introduced. Are they so expensive to produce that you have to use the larger denominations to subsidize the smaller, or what?
I was hoping the surcharge would drop low enough that I wouldn't feel like a sucker buying ฿1 bills. 0.100 over face value would have seemed reasonable.
We did increase the fee for the ฿20 bill. We feel that it's important to integrate stronger security features, including custom holograms, as early as possible. However, we need to finance the high capital costs associated with these improvements. During this period of particularly high demand for Bitbills relative to our supply, we've decided to increase the fees a bit as a fundraising measure. The ฿20 bill was the most natural product to raise the fee on, since the new fee brings it's percentage surcharge closer to that of the other bills.
As production continues to ramp up in the next couple weeks, definitely expect the fees to go down. We may also consider switching to set fee across all denominations.
