YOU CAN SEND UNCONFIRMED BTC
This is how you send fake bitcoin transaction
1 You input the sender and receiver’s bitcoin addresses 2 You as well input the amount. 3 Then click on “Generate“. 4 The software will give you a live blockchain link to track the transaction, making it look real. But the transaction disappears after 12hours. Meanwhile, 12hours is enough to trick anyone, isn’t it?
This is a little technical but what happens is when someone tries to submit the transaction from his wallet to yours, you’ll see BTC start appearing in your wallet even though (s)he doesn’t have enough BTC to pay you. But due to the verification process, they’ll appear as unconfirmed BTCs. Unconfirmed simply means that someone has intended to send you BTC but the transaction submitted by the sender has not verified in terms of valid transaction. Validity clause would be like, the sender has enough BTCs to do this transaction? Since sender doesn’t have enough coin in his\her wallet, this transaction would be invalidated and later, unconfirmed BTCs would disappear from your wallet. But if you are doing digital product delivery or service, you may get to know later that someone has paid you the “fake” BTCs.
