So i was thinking if i send a bitcoin transaction without the miner fee or a very low fee what will happen ? would i get the coins back eventually ? or they will just stuck there forever ! and if that happened how to do that double spend ?
I think in that scenario, it is not possible that there will be no miner fees in doing transactions because miners are being payed to process transactions. Transactions with highpayment of transaction fee seems to be the first priority because maybe it is an indication that the transaction is urgent and important. Your money won't be stuck there because as soon as they finished the first priorities. But if you can't no longer wait, you can pull out your transaction. But if you want to process your transaction as soon as possible, pay the right amountn or pay large fees.
To be honest, I have never experienced any difficulties with the payment of transactions by Shakhtar. The fact is that as the system issues numbers, So I send. On the one hand It's all small things, The main thing is that everything went well. Perhaps I do not yet have much understanding of this matter, but for today I have not yet encountered problems with the conduct of their transactions.
