No bitcoin confirmations

1. The amount of transaction is different, the number of confirmation is also different
in addition, the amount of handling charge also determines the order of transaction confirmation
so, yes, you made it. But it will take time to confirm.

2. Wait a minute,

3. You are right. Indeed, it will be rolled back. If the transaction is unfortunately packaged on the fork, the transaction is likely to be cancelled after the main chain is synchronized

the reason why we need six confirmations is that it is more difficult to obtain the optimal solution (to prevent single node fraud). One block may also be able to get an optimal solution, and it is basically impossible to get six blocks together. It has nothing to do with bifurcation

4. Generally, only the payee can return bitcoin after 24 hours. Any bitcoin transaction is irreversible and can only be returned by the payee.

5. Radar coin will, bitcoin did not encounter this situation!

6. No, the transaction that belongs to you, that is, your utxo will be saved to your bitcoin wallet file, and each payment will be found from your wallet database. If you lose the contents of your wallet, you can use your key information to access the service node to retrieve your utxo. If you lose the key, don't worry.

7. This is very difficult to find. Failure to confirm is proof of the failure of this transaction and failure to obtain confirmation from the network. Bitcoin receives payments almost instantaneously. However, there is an average delay of 10 minutes before the network starts adding your transaction to a block to confirm the transaction and that you can use the received bitcoin. Confirmation means that there is a consensus on the Internet that the bitcoin you receive is not used to pay others, so it is recognized as your property. Once your transaction is included in one block, all subsequent blocks will include it, which will greatly consolidate this consensus and rece the risk of transaction cancellation. Each user can determine the time when the transaction is confirmed, but generally speaking, receiving six confirmations is as safe as waiting six months after a credit card transaction

however, foreign studies have also shown that these bitcoins can be tracked and retrieved, but they are troublesome. At present, they are still in theory, and no company provides such services. Bitcoin house has this convenient report. You can check it on it.
