Do I Have to Change My Seed after Multiple Transactions?

Question

Is it recommended to change the seed and transfer the funds after creating a higher, specific amount of Receive addresses and doing multiple (20+), completed transactions (no double-spending of course)?

Or is it safe to use one and the same seed for many transactions as long as you do not double spend and properly follow the wallet instructions.

Answer 1

It's safe to keep your seed. Even if you double-spend or reuse your address, your seed doesn't get exposed, only the private key of one address of your seed is partially revealed. You can generate an infinite amount of addresses with one seed.

• What's the difference between a private key and a seed?
• What is the difference between "double-spending" and "address-reuse"?

But there is one reason, why you should maybe change your seed after every snapshot:

After a snapshot, a stateless wallet (like the current official IOTA Wallet 2.5.6) does not know which addresses it already used and which it didn't. So you could accidently reuse an address.
