RACOOIN._transfer(address,address,uint256) (#805-841) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(_lastBuy[to] + _buyCooldown < block.timestamp,Must wait til after coooldown to buy) (#819)
RACOOIN.addLiquidity(uint256,uint256) (#885-901) uses timestamp for comparisons
Dangerous comparisons:
- ethAmount - ethFromLiquidity > 0 (#899)
Avoid relying on block.timestamp.
