- Software should prevent the creation of an account if a previous account does not have a transaction history (meaning none of its addresses have been used before).
But I can easily create an account even if the previous account is empty.
- Address gap limit.
I can also see that the amount has reached the account, in which there are many more consecutive addresses without a transaction history, even if the amount is sent to the address after those addresses without a transaction.
Addresses created by the command: bitcoin-cli getnewaddress <account>
