XrpTiger._splitOtherToken() (#1253-1299) ignores return value by doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1281)
XrpTiger._splitOtherToken() (#1253-1299) ignores return value by doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1292)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Attempt to swap token was unsuccessful. For some reason it is untradeable. If token is not in presale stage and is not traded outside PancakeSwap, then it's a scam

Additional information: link

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.

Token is deployed only at one blockchain

Token has only one trading pair

Unable to find website, listings and other project-related information

Young tokens have high risks of scam / price dump / death
