How many addresses can I have in Bitcoin core?

[dennis200222]

Hello,

so yeah I intend on doing trades throughout the bitcoin world and would require thousands of addresses I was wondeirng how many you can have per wallet? hopefully at least 1000 per wallet. all of these would probably be labelled too if that makes a difference

and also what is the performance like when you have hundreds of addresses?

You can have as many as you want with whatever labels you want. You can have several thousand of addresses. Just remember that the more addresses you add the bigger your wallet file will be.

Thousands might make sense, but it will eventually cause performance loss. More transaction data, more outputs that a client/wallet will care about, more network traffic, and more results to bloom flitered requests to nodes. Of course, if you're handling thousands of addresses in an automated manner on a website (not as a direct user of a wallet) you might consider writing code more specific to your use-case, for example using bitcoinj as a library.
