Does Anyone Know About This? {Smart Contract Ethereum}

[my dream2021]

Hello..........

I am so sorry if I ask here coz I try to find the answer on internet but still not get that, so I feel very grateful if anyone can answer it.

Yesterday on (Aug-04-2019) one of token make me confused cuz how can be Dev smart contract eth control the cycle of token (I means pull back they token from cycle of wallet eth ppl) and did you think Dev too will be pay gas ? also how we know for sure if token on CMC can't be like that.

This smart contract https://etherscan.io/token/0x339da9e0cb5a4f44e74cbcfdd394d707e6315545

it is very possible, because in the smart contract of the token you mentioned that have "TokenFallBack" function,
which means the contract creator can redeem the token

and I think the one who pay fee for the gas is coming from smart contract
I just see some tx hash and the gas is payed by smart contract

The dev did it because the gas will always be needed when you are starting the use any feature that available in the blockchain. The dev can control it through the code that already issued in its smartcontract and the dev has access to that smartcontract dude.
