Hello all,just asking about gas when we send erc20 tokens..it's always say that minimum limit for gas is 21000,but i put 120000 for fast transaction but always fail status,the my ethereum balance was less..so guy,am asking if we did transaction and even failed we need to pay gas??even failed transaction ? I try to transfer my tokens from mew to another erc20 but always failed and say transaction successfully foind but the smart contract is locked..why locked?

you need to learn more about gas - https://media.consensys.net/ethereum-gas-fuel-and-fees-3333e17fe1dc
to send ETH - gas limit 21000 and gas price you can see in this website - https://ethgasstation.info/
if you send erc20 token gas limit will be more, depending on the smart contract.
