Food for thought:

Consider a transaction at the highest rate (25%).

'withdraw 1000'

At the completion of the transaction, the customer has 750 coins, and Nenyuk is 250 coins richer. Was this really a 25% tax or a 33% tax? Are you paying a fee to withdraw the fee, only to hand it right back across the counter?

Locking this thread because it has gone off topic.

Nah, I'm kidding, check out this other thread on new changes.
