Welcome, I am new here. I want to ask the question of how millions of Bitcoin addresses worked for personal use for a project without mentioning what it is and linking addresses to a single wallet such as a blockchain. Any money transfer to any of these addresses turns into my account. I know the use of a private key. For Bitcoin addresses, but it will be tiring to make 10,000 addresses and link them, so what should I do when I do not want to use the API system This project has some suit because it is a stupid blockchain system. Sometimes it closes the API and the project that will be created cannot be linked to the API permanently. Are there ideas and solutions?
