Can you cancel BTC transaction with 1 confirmation?

[pakhitheboss]

After one confirmation you cannot cancel a Bitcoin transaction. The only option now left is to contact the individual to whose wallet you made that transaction.

Always keep in mind with Bitcoin after one confirmation you can never reverse, recall or cancel it.

Bitcoin transaction is irreversible (can not be reversed), can not be canceled after you sent it. Only the receivers can refund your bitcoin (with deduction for transaction fee of 2 transactions back and forth.

No, of course but with one confirmation bitcoin records or the transaction being made could be deleted erased in blockchain as the miners could easily wipe out data and replaced with other data. This is why it is ver important to get more bitcoin confirmations as it determines the depth of the blockchain records being kept. If records kept in shallow portion then as I mention above it could be deleted, replaced or changed by other transactions that could fit into that block that based on my understanding.
