As mentioned previously, there is a 12%-14% transfer tax on each transaction, the 10% transfer tax will be sold to get BNB through the contract automatically. Every time the total of this transfer tax exceed 50,000 THOREUM the contract will automatically sell 50,000 THOREUM for BNB and adding to Thoreum's contract. This number (50,000) can be changed depend on the price of THOREUM.
