Trading volume is essential to SAV3.
If possible, pursue special listing processes with CEXs (e.g. Binance, Huobi, Coinbase, etc) where such listing won't negate SAV3's tax policy. Collaborating exchanges could report daily volumes and burn SAV3 accordingly.
Either way, come up with methods to increase trading volume. The buying tax goes against trading volume as casuals won't understand that you need to increase slippage to at least 9%. Address this.
