It is very important to introduce impact tax, otherwise known as
Anti-Dump Algorithm or Anti-Whale Dump algorithm
Tax will be added based on the price impact of the sell.
For example, current sell tax = 16%,
trying to sell with 0.1% price impact, 16% + (0.1% * 4) = 16.4% tax is applied
trying to sell with 1% price impact, 16% + (1% * 4) = 20% tax is applied
