Minus Tax System

All tokens these days have tax at buy and sell.
I understand for the tax at sell.
But why BUYERS have to pay tax?

So I invented this concept.
Tax is minus. yes. MINUS. not even ZERO.

-10% tax will be applied to each buy.
Which means you will get 10% more tokens in every buy.
Investors will be more motivated to buy the token.
Growing the token and the community.

And this is possible by getting the tax from the sellers.
Portion of the tax at every sell will be saved to provide -10% tax.

Concept may be very simple and intuitive.
But implementing this is quite difficult.
It is not a matter of just copying other tax tokens code and setting tax value to -10.
You need extra token pool,
calculate the theoretical maximum amount,
and carefully divide portion of the tax to the pool... etc
Will skip the details in here.
Anyway, the conclusion is, I made it. Working very well.
