So I have seen a few people sending bitcoins without any miner fees, and their amount eventually got sent back after a week or so.
Thats bc.i specific behaviour, coins dont "get send" back usually.
So, what do you think the technique(or tips) for sending bitcoins without miner fees would be? This would be really helpful for sending small amounts less than BTC0.001 since the transaction fee would be more than 10% of the real amount transferred.
Inputs of 1 Bitcoin with 144 confirmations (~1 day) typically have a high enough priority to be used in a transaction with a single output to be confirmed in a reasonable amount of time. Thus if you want to spend 0.001, just wait 1000 days, pay the fee or use an off chain system like changetip.
