I have some small amount of ethereum on one of the addresses and a perfectionist in me wants to move the whole amount to a different address, leaving exactly 0 ETH on this one. Is there a sure way to do it? To factors are unclear to me:
When I specify an amount for transaction, would it be amount before the transaction fee (so I cannot take all the sum) or I just say “send all” and the fee will be automatically deducted from the amount arrived
Gas price changes, so you cannot be sure about exact fee, right?
