I want to buy some BTC with cash locally, the seller i found says : "send BTC to your wallet. After 1 confirmation On blockchain, collector takes from the table cash."
Is this enough to be sure i will receive the bitcoin sold me? Or its better to wait for 2 confirmations?
To be safe you need to wait to get 1 confirmation first, because the transaction might fail and the funds return to the seller if you
haven't received a confirmation, make sure that there is an entry funds in your wallet first.
