What is the best way to generate bitcoin wallet?
What is the safest way to generate bitcoin wallet? From the existing software such as bitcoin-core? electrum?


Ensure you are using open source hardware and nothing is backdoored. I am not an expert but Luke Dashjr might help you with this considering some interesting tweets in past.

Ensure there are no malwares on system you use for bitcoin wallet. You can also use virtual machines or Qubes OS to keep things separate. Example: One virtual machine for bitcoin cold storage, One for hot wallet, One for social networking, One for office related work etc.

Don't use VM images from random sources, it can be backdoored: https://www.reddit.com/r/Bitcoin/comments/jrxgj8/bitcoin_core_node_hacked/

Use open source bitcoin wallet with more usage and active development, compile it yourself after reviewing the code for important things atleast: https://bitcoin.stackexchange.com/a/99480/

Create multiple backups for your wallet, test those backups and keep them safe.

Do not enter seed or anything on any website that helps other people get access to your bitcoin. Avoid entering seed on any online device.

Use hardware wallets like Coldcard if you find them safer compared to other things.



I also read that bitcoin-core is not using BIP39 because it is not sure, but why BIP39 is still used in many wallets?
