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?
yes it is also possible to buy Bitcoin normally without any bank accounts and I don't think it is trusted but if you don't have any other way then you can really use this way to change your money into Bitcoin
