I accidentally sent a payment from my blockchain.info address to my Bitcoin Core address with a really small fee (5 satoshi/byte). The transaction is still currently unconfirmed, for 4 days now.
I heard Bitcoin Core has mempool.dat, but I'm unsure if this tactic works only if you sent the TX from Bitcoin Core.
If I delete my mempool.dat, will that send the bitcoin I sent back to me on blockchain.info? I'm sending my bitcoin to my Bitcoin Core address that has the mempool.dat. Let me know. Thanks!
