Contract ownership is semi-renounced (passed to a contract)

Number of Binance Smart Chain (BSC) token holders is less than 100. Token is either dead or inactive. Ignore for presale.

Average 30d PancakeSwap liquidity is low.

Token is deployed only at one blockchain

Token has only one trading pair

Contract has 12% buy tax and 12% sell tax.
Taxes are high (over 10%) but contract ownership is renounced.
