Just try to sent some shit tokens with zero gasprice and let us know that it's success transfer or error , I never do this because i scare with error message and don't know what will happen
You can override your transaction with a new one with a higher gas price. When you check the gas prices on https://ethgasstation.info/, the safe low always works.
Since nobody posted an answer I will test this when the network load is low.
lol until you are old you do not accept your ETH. if you want fast and not too expensive you can use gas price 41 gwei this is minimal and delicious in my opinion
This was not the question. I asked explicitly for a zero gasprice transcation. The minimal gas price for a fast transaction is also not always 41 gwei, the more transactions you have the more people will pay and therefor you have sites like https://ethgasstation.info/
