TelegramX.difidendToLPHolders() (#445-468) ignores return value by IBEP20(usdt).transferFrom(address(_usdtReceiver),lpHolders[i],reward) (#465)
TelegramX.claimLeftUSDT() (#469-472) ignores return value by IBEP20(usdt).transferFrom(address(_usdtReceiver),wallet1,left) (#471)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

TelegramX.difidendToLPHolders() (#445-468) uses a dangerous strict equality:
- reward == 0 (#463)
Don't use strict equality to determine if an account has enough Ether or tokens.
