“The only way to confirm the absence of a transaction is to be aware of all transactions” – Satoshi NakamotoGeneral Info:There are various types of wallets where users mostly sends Bitcoin for example: Any Bitcoin wallet and exchange wallet.
Many people believes 0 confirmation transaction are reversible.
- Bitcoin Wallet (while receiving/sending)(mainly for 0 to 10K USD tx): Wait for at least 2 confirmation.
- Exchange wallets (depends on their requirement): 3 confirmation
- Sending more than 10K in USD: wait for at least 10 confirmation
Transactions with 0/unconfirmed can be reversed with not too much cost via Finney attack and race attack, but in some cases may still be acceptable especially for low-value goods and services, or ones which can be clawed back.
