Holders:


Average 30d PancakeSwap liquidity is less than $100. Token is either dead or inactive.


Average 30d PancakeSwap volume is less than $100. Token is either dead or inactive.


Average 30d number of PancakeSwap swaps is less than 1. Token is either dead or inactive.


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


Average PancakeSwap trading volume, liqudity, number of swaps are extremely low. Token seems to be dead.

Contract has 4% buy tax and 2% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.


Token is deployed only at one blockchain


Token has only one trading pair
