* @dev SLUFFY transaction will be charged an 8% fee, including:
* @dev ? 4% Reflection, spread across all holders except for team's wallet.
* @dev ? 2% Team funding, team's wallet will have no initial fund and has to earn them accordingly to SLUFFY success.
* @dev ? 1% Burn, making SLUFFY a deflationary token since it becomes scarcer overtime. -> price goes up.
* @dev ? 1% Re-add back to pool for liquidity.
*
* @dev SLUFFY 100% total supply is spreaded as following:
* @dev ? 95% Handled by DxSale for IDO.
* @dev ? 5% Marketing wallet initial fund.
*
* @dev Reasons why SLUFFY is a safe and stable investment
* @dev ?️ Contract ownership is renounced after IDO.
* @dev ?️ Has a maximum transaction limit to avoid whale.
* @dev ?️ Our team initial allocation is relatively small compare to the overall supply.
* @dev ?️ Liquidity is locked for 3 years after IDO.
* @dev ?️ Fee is immutable since it's a constant value.
