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 ?
Well, the transaction will uncofirmed so long, maybe you need to wait until 1 month(?) and your transaction will canceled and get your coins back, cmiiw. I think it will get confirmed even you use very low fee, but you need to wait until 2weeks-1month.
