MekaMiners.constructor(address).feeReceiveAddress (contracts/MekaMiners.sol#25) lacks a zero-check on :
- _feeReceiveAddress = feeReceiveAddress (contracts/MekaMiners.sol#27)
Check that the address is not zero.

MekaMiners.transfer(address,uint256) (contracts/MekaMiners.sol#104-140) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)((_lastTrade[_msgSender()][_receiver] < (block.timestamp - _tradeCooldown)) && (_lastTrade[_receiver][_msgSender()] < (block.timestamp - _tradeCooldown)),No consecutive sells allowed. Please wait.) (contracts/MekaMiners.sol#122-128)
MekaMiners.transferFrom(address,address,uint256) (contracts/MekaMiners.sol#142-169) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)((_lastTrade[_from][_receiver] < (block.timestamp - _tradeCooldown)) && (_lastTrade[_receiver][_from] < (block.timestamp - _tradeCooldown)),No consecutive sells allowed. Please wait.) (contracts/MekaMiners.sol#153-159)
Avoid relying on block.timestamp.
