As you can see from web3.eth.getTransactionReceipt

  transactionIndex: 151 }

the status is 0x1, meaning success. However, the gas limit was low(50k) for this transfer. So, what exactly happened there?

I think I figured it out:

aigangToken.methods.balanceOfAt('0x1f38ac62e62ecbc08e124297f84165b5f61cc96b', 4891051).call().then(console.log)

The sender didn't have any token balance.

So, Since the sender didnt have token balance, the tx simply executed this return: https://github.com/AigangNetwork/aigang-crowdsale-contracts/blob/master/contracts/MiniMeToken.sol#L220 Therefore, it was successful transaction
