Contract ticker (YAIBA INU) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

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

Contract has 7% buy tax and 7% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.

Average 30d PancakeSwap liquidity is low.

Average 30d PancakeSwap volume is low.

Token is deployed only at one blockchain

Token has only one trading pair
