So for the gas. I leave the Ether at 0 and send the default amount of gas that it shows. Or can I lower the gas amount?
It's showing me Gas Limit 50699.
Best to go with the amount of gas that Myetherwallet automatically calculates.
You risk having a failed transaction if the gas amount is too low.
You can manipulate Gas price (not limit) in Gwei and transaction costs goes down but sometimes you need wait longer.
