When someone sends you bitcoins, they are essentially creating a new transaction and adding it to the blockchain. This transaction will remain in the blockchain forever. However, there may be cases where a transaction disappears from the blockchain.
There are a few possible reasons for this:
The transaction was never broadcast to the network: If the person sending you bitcoins never broadcasts the transaction to the network, then it will never be confirmed and will eventually disappear from the blockchain.
The transaction was not included in a block: Transactions are only confirmed when they are included in a block. If a transaction is not included in a block, it is said to be unconfirmed. Unconfirmed transactions will eventually disappear from the blockchain if they are not included in a block within a certain period of time.
The transaction was invalid: If a transaction is invalid, it will be rejected by the network and will not be confirmed. Invalid transactions will also eventually disappear from the blockchain.
The transaction was overwritten: In some cases, a new transaction can overwrite an old transaction. This can happen if the same inputs are used in both transactions. When this happens, the old transaction will no longer be visible in the blockchain.
