BDIP17 (Formal vote): Tax bad actors (transactions away below $1 peg)

This is similar to the current proposal under consideration by https://mith.cash/

The idea behind this proposal is to create a disincentive for sellers of BSD on BSD trades below $1. By corollary, this creates an incentive to:

1. Buy BSD when BSD trades below $1.
2. Buy or sell BSD when price is at $1 (and above).

This could be a variable tax rate: 5% of transaction value on BSD sellers on all BSD trades below $1 10% of transaction value on BSD sellers on all BSD trades below $0.90 15% of transaction value on BSD sellers on all BSD trades below $0.80 20% of transaction value on BSD sellers on all BSD trades below $0.70 25% of transaction value on BSD sellers on all BSD trades below $0.60 30% of transaction value on BSD sellers on all BSD trades below $0.50 35% of transaction value on BSD sellers on all BSD trades below $0.40 40% of transaction value on BSD sellers on all BSD trades below $0.30 45% of transaction value on BSD sellers on all BSD trades below $0.20 50% of transaction value on BSD sellers on all BSD trades below $0.10

What happens to the tax? The tax is only imposed on sellers of BSD (when BSD is below $1). The tax proceeds will go to the DAO to be used for incentives e.g. to reward BSDS holders.

Implementation challenge: This will likely require a change in the token code such that the tax happens based on the exchange function. It could be that the tax always happens and a rebate is returned if the oracle price shows that BSD >= $1.

Advantages:

1. Clear disincentive / penalty on BSD sellers when BSD is below $1.
2. Increased demand for bonds, as BSD holders (when BSD is below $1) is faced with 2 alternatives: (a) Sell and be taxed, or (b) swap into bonds (no tax).

Disadvantages:

1. Likely requires new token contract.
