OSDcoin._transfer(address,address,uint256) (#613-650) uses a dangerous strict equality:
- shouldSetInviter = balanceOf(to) == 0 && inviter[to] == address(0) && from != uniswapV2Pair (#632-634)
OSDcoin.setShare(address) (#684-692) uses a dangerous strict equality:
- IERC20(uniswapV2Pair).balanceOf(shareholder) == 0 (#686)
OSDcoin.setShare(address) (#684-692) uses a dangerous strict equality:
- IERC20(uniswapV2Pair).balanceOf(shareholder) == 0 (#689)
Don't use strict equality to determine if an account has enough Ether or tokens.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

OSDcoin._transfer(address,address,uint256) (#613-650) uses timestamp for comparisons
Dangerous comparisons:

Avoid relying on block.timestamp.
