What happens if you send a payment and have your wallet set to pay zero mining fee? Do the transactions just not get added to the blockchain?
Also is the mining fee taken out of the amount of btc sent (e.g. btc sent - mining fee = amount received) or is it added on top of the btc sent and taken from the remaining wallet balance (e.g. btc sent = amount recieved and mining fee taken from wallet balance)?
Hope this makes sense to someone
