Scanner of Bitcoin wallets

Writing for himself a bot, to find all the bitcoin addresses belonging to one person, by checking where to go the transaction delivery, the bot also gives information about the wallets from which the user received the money and where he sent them, in order to save resources the bot checks only the last 200 transactions. There’s no database in it because it’s an old job, now naturally all my bots only with a database. It works naturally on requests.
